I always report posts that I think are generated by trolls - they are usually very easy to spot and a mile away from the heated debate that sometimes takes place on GN. If you value GN as a reasonable, moderate place to debate, then don't try to argue with trolls. If you give them the oxygen of attention, very soon the GN you know and love will be swamped and obliterated by the most vile and moronic contributions you can imagine. I think that by reporting possible trolls, and leaving it up to GNHQ to arbitrate, we are preserving GN as the place we know and value. If some people think this is snitching to teacher, let them take their contributions to a different forum that is not so well moderated.
