The chat crashing is different from the chat "being hacked" - which implies that someone did something malicious to cause it to do something that it doesn't normally. As far as I know that hasn't happened to chat. Assuming someone does manage to do that, the best thing to do would be to send a message to Special:Contact/bug with as much information as possible on how it happened, this gives Wikia more information to help fix the problem.
