Apparently, according to Mallace, this isn't already a rule. We need to make sure people don't abuse the "!mods" ping in chat. It should only be intended to notify mods/admins of a problem or a question only they have the solution to, like rule-breaking. I'm not suggesting we give those guilty of this a tremendous punishment, but if they're asked to only do it when they need mods/admins and they continue to abuse it multiple times, then, after being kicked for it already, they should receive a strike.
Also, we should probably put on the chat page that mods and admins can be pinged with "!mods"
