Seriously I can't stand this agency trend either, especially the accounts that follow you back, they can kindly fuck off. Its far worse on Fansly, at least in my opinion, which is just oversaturated with these Google translate English, online 24/7, follow you back, constant spam messge accounts. Funny thing is I am pretty sure its against terms of service, at least on Onlyfans to allow someone else to run your account.
My rule of thumb for Fansly at least is that if they have more than 1 - 2k followers, and are from eastern Europe (including Russia/Ukraine) I avoid, because, its going to be a bad time.
