I've worked with image software for years and no amount of compression, cropping, saving and recompression has ever produced anything even remotely similar. It looks like someone scanned in an old fax that had been refaxed a billion times. It just defies everything I think I know about image compression algorithms. I see text based images like this 10 times a day and I'm at my wits end trying to figure it out.

Someone please explain to me, this bullshit right here:

I think Facebook just always runs a low-pass filter whenever you upload, whereas saving to jpg format is essentially a nilpotent operation (e.g. if it's already jpg compressed then saving as jpg with the same compression causes no change), which explains why you can't reproduce the effect.

These are good, thank you.
