I agree, the spammy one liners are really annoying. There’s a guy I see in many hosting related forums who does that even more excessively and Powweb removed his signature lol.
Newbie is also a very blatant and dull way of influencing a discussion. I can’t remember the username but there was another user who came in with 0 posts to offer defense in a post where Itay came under fire. Probably discussing his merits from setting up the blackhat conference.
