BanThisGuy

This bot can not only ban, but also automatically re-invite the user and restore any roles and nicknames they had beforehand, giving you the ability to really send a message without doing any of the work! It also features several customization options allowing you to pick certain phrases to trigger the bot and send a gloating message afterwards for extra emphasis. To use the bot, simply reply to any message with the default phrase "Can we ban this guy" or any custom phrases you may have added.
