Y99 は安全に使用できますか?
Y99 is only moderately safe. Guest access and anonymous usernames make it easy to join, but also easy for people to misrepresent themselves, and because Y99 doesn’t state a minimum age, you can’t assume everyone in a room is an adult. Treat it as an open public space.
- Stay anonymous. Use a nickname that doesn’t reveal your real name, location or age.
- Never share contact details, photos or social media handles with strangers.
- Assume rooms are mixed-age. Adults should keep conversations appropriate and leave any chat that turns sexual.
- Ignore off-site invitations. Be wary of anyone pushing you to another app or asking for money.
- Walk away from hostility. Stop replying and leave any room that turns aggressive.
