This would work, but I would make one more change; implement the /ban feature now. I agree we don't really need it yet, but we won't know ahead of time when we will need it. However, I think it might be better to use something other than a traditional "ban".
I can think of two possibilities, either of which would work pretty well;
1. Implement a /ban that lasts somewhere between 1 hour and 24 hours. (12 hours?) The /ban can be implemented by any bishop or higher. It's unlikely that any of our bishops will be judged unsuitable; if enough people complained about misuse of the /ban by any specific user, I'm sure vroom would be willing to block that user from the function.
2. Implement the /ban on a voting system. If more than half of the current users (those listed in the "Other Users" box) /ban a user, that user is banned for 1 hour. The ban is short enough that most abusers won't be willing to hang around long enough to keep it permanent; the group here is, I believe and sincerely hope, not rotten enough to be able to implement too many unjust bans, anyway.
What do you guys think?
