I haven't seen the name American Tanker/Thomas Nair come up here, but he might be the best example one could think of. He started his account 6 years ago, but I don't remember when he was finally banned.
Dude hated My Little Pony with a passion back when it was still a growing phenomenon and often caused more trouble than was needed over a simple pony reaction image. He was banned for not being friendly, but that took a long time for us to actually do it. If I remember correctly, I deactivated him (I thought I banned him, but I don't see a record of bans for him), but it was a community decision after we had said he couldn't be disruptive anymore. He said he wasn't going to change, he didn't change, and we went with it.
In a way, it was similar to Lisa, but Lisa got legitimately banned for avoiding a suspension. Nair got banned for consistently breaking the same rule over and over.
But he was certainly a member of the community.

He died with over 3,600 forum posts and more than 260 comments. His second to last post.
I think I said that, because I was wondering why he'd still talk poorly about ponies, because I didn't want to ban him, but it seemed like he was ready to be done with KYM. Maybe it was a mutual understanding that he was on his way out, one way or another.
