My theory is that they think it would lead to a lot of trolling.
Like posting 0-16 Lions fans paper bag heads.
Lol, just for example.
But you know what I mean. They lie and say it's for something about server speed which is TOTAL ****ing ********. The images don't use bandwidth from their servers, only from where they are hosted at. Not only that, like I said, those huge GIFs, I have a .5mbit DSL at home. I can barely watch YouTube and yes those are annoying as **** when they are like 5MB but I don't really notice it. I can't imagine I would have huge issues with images. I'm sure there are FEW people with worse internet than me on this website.
Posting funny pictures like that and internet memes and such is half of what makes message boards fun. This place is lame. I got an infraction for posting a picture.
