Parents looking for a list of websites to block for kids usually want a simple blacklist. The problem is that the web changes too quickly for one permanent list to stay accurate. Domains disappear, new clones appear, and mainstream platforms can contain both useful and age-inappropriate content.
A better 2026 strategy is to combine a short list of known high-risk sites with category filtering for adult content, gambling, random chat, risky downloads, and other 18+ spaces. This guide explains which types of sites deserve the most attention, which popular platforms need age-based decisions, and how to build a practical blocked-websites list for kids and teens.

Part 1: What Are “Sus” or Inappropriate Websites?
“Sus websites” is informal slang for sites that look suspicious, unsafe, misleading, or inappropriate. For parents, that can include sites that expose children to explicit material, strangers, gambling, scams, aggressive advertising, dangerous downloads, or communities with little age-appropriate moderation.
Instead of asking whether one website is universally “bad,” look for risk signals:
- Adult-only or 18+ access: dating, pornography, sexual-content, or gambling services.
- Random stranger matching: video or text chat that connects users with people they do not know.
- Anonymous posting: communities where identity and accountability are limited.
- Mature user-generated content: social platforms that allow adult themes even if they also host normal content.
- Untrusted downloads and redirects: sites with fake buttons, pop-ups, mirrors, or unknown files.
- Weak age fit: platforms whose own terms say they are for adults or older teens.
Important: blocking decisions should be age-specific. A platform that may be manageable for an older teen with the right settings may still be inappropriate for a younger child.
Part 2: 10 Websites and Site Types Parents May Want to Block
This is not a universal blacklist. Use it as a starting point and adjust it to your child's age, maturity, browsing habits, and your family rules.
1. Adult and Explicit Websites
If your goal is to create a porn sites list or a list of 18+ websites, avoid relying only on individual domains. Adult websites frequently change domains and mirror addresses. A category-level Adult filter plus selected URL blocks is easier to maintain.
2. Monkey.app
Monkey is a random video-chat platform. Its current Safety Center states that it is strictly for users 18 and older. That makes it a clear candidate for blocking on children's devices even though the service says it uses AI moderation.
3. Tinder.com
Tinder is designed for adults. Its current Terms state that users must be at least 18. Parents should block the website and app for children rather than relying on an age claim entered during sign-up.
4. 4chan.org
Anonymous image boards can move quickly between ordinary discussion, shocking imagery, adult themes, and offensive material. For younger users, blocking the domain is generally simpler than trying to supervise individual boards. Learn more in FamiSafe's 4chan safety guide.
5. X.com
X permits consensually produced adult content if the media is marked as sensitive. That does not make X an adult-only website, but it does mean parents should review whether the platform fits a child's age and whether additional filtering is needed.
6. Reddit.com
Reddit requires users to be at least 13 globally, with higher requirements in some regions. Mature 18+ communities are age-restricted. Because Reddit contains millions of user-created communities, parents may choose full blocking for younger children and supervised use for older teens.
7. Tumblr.com
Tumblr currently allows some mature content under content labels, while visual depictions of sexually explicit acts are prohibited. Users under 18 cannot click through to mature blogs. Families may still decide to block Tumblr for younger children because mature themes can exist alongside general-interest content.
8. Gambling and Betting Sites
Online casinos, sportsbooks, betting sites, and real-money gambling services belong on most children's block lists. Because gambling domains change frequently, category filtering is more practical than maintaining a manual list one URL at a time.
9. Piracy, Mirror, and Suspicious Download Sites
Free streaming mirrors, cracked-software pages, and unknown download sites can expose children to misleading buttons, aggressive pop-ups, redirects, phishing, and potentially unsafe files. If a child only needs legitimate entertainment or software, blocking these categories reduces unnecessary risk.
10. Omegle-Style Random Chat Clones
The original Omegle service shut down in November 2023, so an article that still presents Omegle.com as an active 2026 platform is outdated. However, the underlying risk has not disappeared: other random-chat and Omegle-style clone sites still connect users with strangers. Parents should block current random-chat services and use category filtering for new clones.
Part 3: Websites to Block for Kids vs. Teens
A useful blocked-websites list should change with age. Younger children generally need stricter allowlists, while teens may benefit from a mix of blocking, age-appropriate access, and conversations about online risks.
Part 4: How to Block Inappropriate Websites
1. Start with Google SafeSearch
Google SafeSearch can filter explicit results in Google Search. For children whose Google Accounts are managed through Family Link, SafeSearch is normally set to Filter by default. However, SafeSearch is not a universal website blocker: it does not control every direct URL, browser, app, or social platform.
2. Use Device or Family Controls
Apple Screen Time, Google Family Link, Microsoft Family Safety, router controls, and school-managed devices can all provide additional layers. Choose the control that matches the devices your child actually uses.
3. Block Categories, Then Add Specific URLs
Start with broad categories such as Adult, Gambling, Drugs, Violence, or other high-risk topics. Then add specific domains when you see a site that does not fit the category filter or needs a family-specific rule.
4. Review Browsing History and Update the List
A blacklist should not be static. Review which sites are actually being visited and update the blocked or allowed list when your child's needs change.
Part 5: How FamiSafe Helps You Block Inappropriate Websites
FamiSafe Web Filter can block websites by category and lets parents add specific URLs as blocked or allowed exceptions on supported devices.
Web Filter
FamiSafe's current user guide lists more than 10 website categories, including Adult, Violence, Drugs, and Weapons. Parents can enable a category block and then use Exceptions for specific websites that should always be blocked or allowed.
Browser History
Browser History can show visited websites and lets parents turn a visited site into a blocked or allowed exception. This helps families build a practical list based on real browsing behavior rather than guessing every risky domain in advance.
Safe Search
FamiSafe also offers a Safe Search feature that can filter explicit content from supported search results. Use it together with Web Filter rather than treating search filtering as a replacement for website blocking.
Conclusion
A useful list of inappropriate websites to block is not just a list of domain names. Sites change, old services close, and new clones appear. In 2026, the most reliable approach is to block clearly adult or high-risk categories first, add specific URLs when needed, and adjust restrictions as children get older. Search filtering, device controls, and tools such as FamiSafe can work together as different layers rather than relying on one blacklist alone.
Frequently Asked Questions
Q1. What websites should parents block for kids?
Parents should prioritize high-risk categories such as adult-content sites, gambling sites, random video chat, adult dating services, anonymous image boards, risky download or piracy sites, and other spaces that are clearly intended for adults. Add specific domains based on the child's age, browsing history, and household rules.
Q2. What are “sus websites”?
“Sus websites” is informal slang for websites that seem suspicious, unsafe, misleading, or inappropriate. Warning signs include aggressive pop-ups, fake download buttons, unknown payment requests, adult content, random stranger chat, poor moderation, or repeated redirects.
Q3. Should parents use a porn sites list for parental controls?
An individual porn-site list is rarely enough because adult domains change frequently. Category-based adult-content filtering combined with specific URL exceptions is more maintainable than trying to block every domain manually.
Q4. Is Omegle still a website parents need to block?
The original Omegle service shut down in November 2023. Parents should focus on current random-video-chat services and Omegle-style clone sites rather than treating omegle.com as an active platform.
Q5. Is Reddit an inappropriate website for kids?
Reddit is not uniformly inappropriate, but it is a public user-generated platform. Reddit requires users to be at least 13 globally, with higher requirements in some regions, and mature 18+ communities are age-restricted. Whether to block Reddit depends on the child's age and family rules.
Q6. How can parents block inappropriate websites?
Parents can combine search filtering, device or router controls, browser restrictions, and parental-control software. FamiSafe Web Filter can block website categories and lets parents add specific websites as blocked or allowed exceptions on supported devices.
Q7. Can Google SafeSearch block all inappropriate websites?
No. Google SafeSearch filters explicit results in Google Search, but it is not a universal website blocker and does not control every app, browser, direct URL, or social platform. It works best as one layer in a broader parental-control setup.
