If we ever have more active users on the site and in general, I think it wise to invest in a system of sorts that allows for more of a process to suppress certain concerning individuals. We could have a vote system on a ban that could be created by a moderator, once enough people vote, something can happen and the details can be approved however they need to, in order to get the user banned.

You might argue that we could exploit this system, but if mods are trusted than that mitigates it reasonably I feel, not to mention mods would create the appeal to begin with. Waiting for an admin to return can mean hours of spam posts or whatever else and I think it would make the whole banning process way less stressful.
