I emailed them last night, requesting the user's information. I have their name, city they live in, and email address [assuming the info is real; if it's not all correct, the money they received from selling off the site should be traceable.]. I'm working on getting a lawyer before I contact them. Conveniently enough, I live in Austin, TX; our art thief is also, supposedly, located in Texas. I managed to find and contact some of the other artists' whose art has been stolen; some of whom have also emailed Spreadshirt.
Here's the info I got from Spreadshirt: James Bennett Frisco, Texas firstname.lastname@example.org
If I can get a case here, would you like me to keep you updated?
Thank you for your help, please do keep me up to date with what you find out. Spreadshirt also sent me the same info and told me that I can contact this person and make him take my stuff down. I noticed other pieces from fellow deviants on his store as well and have contacted them. If this person wants to continue then he will have to deal with my lawyer. I also found the douchebags Facebook page.
Everything on his page is obviously stolen; it's just a matter of picking the right tags to search through to find the original artists. Half the stolen art is zombie related... and there's nearly 700,000 results on here with "zombie" in their tags.
I searched for his facebook too; I got four results, but none of them have enough info visible for me to be sure it's the right person. Although one is from Texas, it says he goes to/went to the community college here in Austin. Frisco, TX is in the DFW area; over 200 miles away from Austin. I'll try to look into it more, I just don't want to accidentally cause problems for someone who just happens to have the same name.
I will definitely keep looking into what can be done and keep you posted.
I went back to his shop just now and it appears that Spreadshirt has removed all of the items that contained my art on it. Guess they actually did something. I still plan on sending this guy a nasty letter regarding art theft....hell I should go after him for any and all money he made off of my stuff. Thankfully my mother-in-law is a lawyer so she can send him a nasty letter as well. But this is his Facebook page for his so called store: [link]
The took everything with my art on it down, too; but I still want to go after everything I can get out of him. Sure, Spreadshirt may removed the designs in question; but that's it. He gets to keep everything he made off of stolen art. His "store" is still up, still selling other stolen art. The only consequence to him is that he now has a slightly smaller inventory, which he will likely just restock with other stolen art. Spreadshirt is keeping everything they made off of anything he sold, too; but they're covering their asses by saying they aren't responsible.
