Don't think it was a one time incident. I saw more than one. I commented to him on the inappropriateness in a followup post to one of the rants. He knew what he was doing, and seemed proud of it. I never reported him to the mods, that's not my place, and I've never reported anybody on any forum. But obviously the mods knew, because his posts disappeared.
@Bacpacker - you didn't let him down, he let himself down. I agree with whatever action was taken to protect the forum. Unfortunate, but necessary.
