It happens, but it's not a major problem. I just had a look through the list of the last 100 threads in General Chat. Not quite a fifth are by escorts. Most of those are clearly not self promotion threads. So I'm not too worried about it. Sometimes people may believe a thread is meant as advertising when it really isn't. There's a tendency when an escort posts something inane for us to assume that that she's just trying to make herself visible. But most threads started by punters are equally inane, and we aren't selling anything.
