>>5756291If you see some guy plastering your work on a mug, or shirt for sale without your permission, would you be fine with it? It's on the same extent with social media, oftentimes the term "repost" means someone who uploads your work without crediting you.
In a way, they're purposely ommitting your name because they don't give a shit about your effort and only want to use your art for their personal gain. Would you be fine with letting those people be?
