Not the forum's fault, it's the fault of individual users.
Don't get me wrong, I use PB too so will have to start using my own hosting more, but I think it's unfair to lay any blame here. If people only uploaded the odd photo here or there it'd be fine, but people (not here in particular) have been spamming the crap out of it with hundreds of thousands of hi-res images.
Hmmmm, what's that I've just seen, is it an announcement?????
The world loves a smart ass
