Just checked the thread you linked to. I consider that rather mild hassling, and the vanity posted deserved criticism, as Jim Robinson regularly tells us to curb the vanities. In fact, in the last few weeks there's been threads about Too Many Vanities. So a vanity consisting of one or two sentences, and also by someone who hasn't been around long, is a target for criticism. The poster being critical may have been not real "nice" about it, but that's FR.
A little rough around the edges sometimes. On FR I have learned to debate with people without losing my cool. It's a useful skill.
"I consider that rather mild hassling..."
I think it is a horrible shame that this assinine, gang of thugs is tolerated as the FR Welcome/Hazing Committee.
