I have not directly been insulted by this person yet, but some of the comments I’ve seen this person post against other people is just sad. Seems like a solid troll. And none of his comments are edited (at least not in a timely fashion - If they have been edited, then it was done a lot later, and his/her comments have probably been read by everyone by then).
He/she seems to be targeting some people, in fact valuable members who always have decent posts, and who don’t make it a business to go around bothering others.
The presence of offensive trollers here is driving people away. No one is gonna post their ideas and values here, and tolerate being spoken to the way Rhuarc has been posting.
