Errrm , yes, TeenKylie, except you don't come out with dumb, well-worn thread-starters like, "I'm thinking of becoming an escort, could anyone give me some advice?" Or "I've just visited my first prostitute [not named] and am having second thoughts about whether I should have done this." Or, "I think I'm becoming addicting to punting and am worried it could ruin my life, what should I do?"
Of course, the occasional post that looks like wank will be genuine, but when a poster makes an odd post that fits the box, doesn't post on anything else, gives no follow up with specific details of who/when, then balance of probabilities can weigh in. Forumites love talking. Easy.
