Ah, I just need to have the most recent bunch of his posts removed from the ingame thread. Although I'm informing him that he's unwelcome in both of the roleplay's threads, I don't find it fair to block him from expressing his opinion. In the event that he starts spamming the thread or griefing us, well... Yeah, that might require further mod intervention.
Either way, the reasons for kicking him are a bit complex. Or, well, not really, but it's not as easy as just saying 'He's breaking the rules, and thus must be furiously kicked in the rear' due to the nature of the roleplay.
I'm making a post detailing the reasons why right now, which I'll link you to if you want to read it. Sorry for pulling you into this.
