The subject(s) of this thread. The "d**kheads who anonymously troll via tags". Been on the receiving end of this myself - and it can be a cowardly way of being offensive. But, as somebody else has said, they are best ignored. It would be best if the facility were disabled. Tags are intended to be useful and informative, to highlight the subject matter. When they are used in the way they are in this situation, and on other threads, they are unhelpful and have little value.
