I don't think anyone will expect you to accept him. Just don't give him leverage against you, okay? I mean, don't make a move, and don't be seen as "picking on" him on the boards. You can be uncomfortable, but don't give him an excuse to get the others on his side, they all seem to be big fans of believing that people change and this is a place for second chances, however kriffing unrealistic that is.
