Actually... Took care of that member just now. That person's a repeat spammer in that they were originally banned under the name Forweddingru, but keeps creating new accounts with a mail.ru email address termination. Additionally, twelping is from the stock of repeat spammers who keep posting nothing but snowmobile-related threads which are equally deleted. The reason you don't see a spammer's posts is the same reason why noone can see their first few posts. When a new member registers, they have to have a certain number of posts approved by the moderators. Until that number of approved posts has been achieved, only moderators will see a given member's posts. Afterwards, everyone will be able to see them. It's a handy tool for getting rid of spam without any cluttering of the forums, which is probably why these spambot jerks keep coming in droves.
Hope this helps explain things a bit better.
