Forum Prevent massive posts aside from setting max characters per post?
 

I have a user who is typing things like "hahahahahahaha" and copy and pasting huge chunks. It's taking up massive real estate and is annoying, especially to our mobile users. Is there a way for me to restrict this sort of thing without setting a max characters per post number? I'm sorry if it's a dumb question, I've looked everywhere and it's escaping me if it is an option.
