Prevent users posting loads of line breaks

[Meirion]

I've got an annoying problem with some users entering massive amounts of line breaks in the posts in order to hide something a lot further down the page. This makes the pages hard to read and is frustrating to scroll through.

Can someone tell me how to hack VB so that after say 5 or 10 consecutive line breaks it won't allow anymore?

Also is there a hack that will chop the lines at xx chars in a post? Another thing is when someone ends a line with loads and loads of !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!! and it breaks the width of the forum. I think that VB already does this feature on the post titles doesn't it? But not in the posts themselves.

Not very exciting I know, but would be very useful to me, and I'm sure some others.

Thanks
