Basically, some people are using signatures that are way too big. I believe that there should be a restriction of height so that the pages look cleaner and shorter. You don't need a big banner, a quote, and an animated banner at the same time.
I am going to use this guy as an example:

Look at the first poster's sig. Yes, it's nice but if he posts 4 or 5 times in the same thread, the page gets a bit bloated with his sig. No offense to the poster of course.
Heck, I even think my sig is a little too big.
I'd say one banner and a single sentenced quote should be the max.
