 -- An extension to moderation.lua. This plugin is useless without it.
 -- Put this at the very top of your plugin list, even before blacklist.lua.

 -- Developed by the incredible JuanPotato, creator of the Python CLI bot Botato.

 -- When a user is kicked for squigglies, his ID is added to this table.
 -- That user will not be kicked again as long as his ID is in the table.
 -- The table is emptied every five seconds.
 -- Thus the bot will not spam the group or admin group when a user posts more than one infringing messages.
