I have a great idea!  Instead of muting beggars, Stunna should make a begging jail.  Then, when someone is begging in main-chat, mods press a button and all that person's chats are directed to the begging jail.  What's more, the only chats that person then sees are other messages sent to begging jail.  The result being that basically the beggars can all be in one place begging from each other---taking a taste of their own medicine without bothering anyone else.  Who knows, maybe they'll actually start funding each others' begs.  In either case, it seems like an appropriate punishment.
