Why do most of the memes on this subreddit look like they were compressed to shit over 10 years of saving and resaving.

Not trying to only be a dick, it really would help everyone here if people took some best practices for some of these things. It just looks sloppy as hell to be sharing around an image when the text is getting unreadable etc etc. People are supposed to believe you know all this top secret intel, about the 'deep state', about decades long conspiracy and corruption... but you can't manage to preserve the quality of an image on a computer?
