Well, I don't use the Chat Room so I can't comment on that. But it does look to me like the mods are helping out, because when I get "Likes" from people on "My Activity," I click on the avatars and find that the accounts are closed.
And when they're not closed and I know that the accounts are bogus, I flag them and move on.
A lot of fake accounts are true. And it seems to me that it's not just about certification. I also quite often receive various requests from them. I usually look at the profile. If at first glance nothing is alarming, I am writing a message. And then I see by correspondence whether it's a fake or a person. Sometimes it was impossible to communicate with real people (different interests besides nudism). Fakes immediately write nonsense.
