And sometimes you can find the pictures because they're still up on the imgur url. Also you might be able to google search images to find collections still online.
Nothing's lost, just harder to find. (more specifically, I doubt anything uploaded ever online was lost because who knows how many people downloaded them and reuploaded them somewhere to their own personal collections. But rather than a easy-access reddit, those mouthwatering jbs are scattered throughout obscure forums onlines)
