I don't think it's a bot, since he responds to posts made about him. And bots usually link to other sites, I think. It looks like he's just a scientologist looking for other likeminded individuals. It also doesn't seem to be a troll thread either, even if scientology is a controversial subject.

I can't close the thread, but I can ban the bot. Thanks for showing.
