How worried should I be about privacy on this site?

I see few people use real pictures. There are lots of IG pics that clearly aren’t them. One girl I already noticed has an AI generated photo of a face, and some just have random nature images or caricatures. Is there reason to worry about people on here knowing anything about the real me? The anonymous feature is used very frequently too which makes me worried everyone is worried about scammers and such so I am using it for now too until I figure out if I can trust people here. What experiences has everyone had with real info about themselves?

Someone told me not to be anon and then blocked me when she answered me anon too. This place seems really screwed up!
