Prevent Numerous Line Breaks

[evenmonkeys]

I have users who like to make five-hundred line breaks because they think it's funny. Is it possible to make a modification so that if they do that, it just erases them? Maybe specify a maximum amount of line breaks they can make? Like... two or three or something...

Still looking for this modification. Doesn't this annoy other people? People who make posts like this:

Hello!!
