Is it possible to have too many external links on your profile?

So, my profile has a couple hundred blinkies, stamps and gifs. I nurture it like a prized collection. But recently, it just hasn't been letting me add more. Like, I import everything like I'm supposed to, I click Save All but it just doesn't save what I just did! 

Could it be overloaded or is it a problem with the website? 

If anyone has an idea, pls lmk. Editing my profile is one of my fav passtimes and I'd hate to have a limit to the madness.
