Recently in f/shoplifting, users complained that languagebot was a little overzealous and asked that it be banned. A mod banned the bot, and the user who made the thread then deleted the thread.
Then an admin unbanned the bot; asking that it be discussed further before resorting to a ban.
Since the original thread got deleted by its OP, here's a thread to discuss how to proceed. Should mods be able to ban bots from their forums?
