He was definitely a sock created for trolling. The fourth known username by this person. His first username had a mix of helpful posts and, ah, not so helpful posts. But after posts of the later type had been reported by various members, he was asked to be nice. His response was that we could ban that username and his IP add, since he had other ones to post from. Higher powers than I called for his spamination at that point. It's too bad he responded that way to the original warning, since he did have some very helpful posts. And it's too bad he's responding with this trolling. It must have taken him a fair amt of time to find new computers w/ new IP adds, generate new email adds and new usernames, and make multiple posts. The only thing one could get out of that is the pleasure from causing other's pain. It succeeded in causing some irritation to various SF members. But any irritation to the mods -- whom he ostensibly would primarily want to irritate -- is minor: It only takes takes five seconds to hit the spam button. And we feel nothing for trolls but pity.
