Have you guys heard about this?
Probably to no one's surprise, there are bots that comb Twitter for pictures that people post that have replies to the affect of "I'd love this on a T-shirt". They then scrape those images and put them on T-shirts that they then sell on their websites. People on Twitter are now revolting by posting obvious copyright infringement images on Twitter (legal) where the bots are scraping them because of the comments and then putting the T-shirts up for sale (super not legal). It's absolutely fantastic, turning the bots against their owners.
