Maximum length for messages in chat

Hello :) 

last week we suffered a very annoying kind of trolling. 

The person copied long texts into the chat. (I think it was even a compound PDF document!). To delete and time out, one had to scroll for what seemed like an eternity. Therefore, there should be a maximum length for chat messages! 

For example, 1000 characters. 

That should be enough characters for all necessary messages, but stop the above kind of trolling.

At the end of the day, a chat is only as good as its management, and a maximum message length can go a long way in improving it.
