This is not a new tactic, but shills who have been detected and marked use the following trick - they simply create new alt accounts, open a topic and then answer the question to themselves, where the answer is of course aimed at the shilling of a certain service.
I wonder what percentage of the threads and discussions on this forum are started by BG shills?

I understand what you're talking about, Lucius. The truth is, for some time now, whenever I see a new thread where a new account talks about BG, I almost always do the same thing, I close the thread (sometimes leaving a post in case the OP wants to contact me), but I don't delete the posts, as there are usually posts from other users that could be helpful. The only way I can think of to prevent this spam would be to take tougher measures, which sooner or later would end up being paid for by users who are not to blame for anything related to this problem.
