If you wanna bypass that 5-minute thing you should try removing a period, remove a space, change up the caps (if that works), do something. Doesn't seem like Shep to give you a role where you can't post more than once every five minutes. He's a nice guy.
DocBlue seems to be playing roughly the same way as usual and as far as I'm aware he hasn't been scum before. It seems like a minor thing to want to lynch him over.
I don't think Shep letting him vote confirms him though, I did do the same thing with MDP in Jobbers (although for the record he was allowed to vote normally). If anyone had asked I would have said I counted it as voting but wasn't necessarily modconfirming him and I assume Shepard would say something similar.
