With some friends we have an idea of an app that would use an adult chat (not porn) just to meet, sometimes anonymously until both parties want it.

my fear is that it can be used in a malicious way, and how can I avoid protecting myself from children using it and worse still, adults taking advantage of it.

Is it enough that I put a tick that "I confirm that I am of legal age"?

Or maybe in my "terms and conditions" clarify that the company is not responsible for inappropriate use. Is it enough to avoid a lawsuit?
