An amazingly effective thing you can do when someone is selling copies of your artwork!

Yes, you can file a DMCA take-down request with the web-hosting company, but it is a bit like whack-a-mole. The offending company can and does just upload more of your artwork -- sometimes they re-upload the same artwork you just took down! You feel you must set a reminder to check the website again in the future and and that the problem has never really been dealt with. I'm going to share with you a brilliantly effective strategy to deal with copyright infringement once and for all (one company at a time).
