I hate MrZachKFC for reselling a bunch of copies of my artwork for like $700, so if you see anyone selling them for a bunch, refer them to save their money and buy one at /warp pink for $100. I don't care if you make tons of copies and give them out for free. Just stop trying to profit from them. :(
as long as your works are original in some way, he has no right to copy or reproduce them. It would be best to inform him to halt producing copies immediately. further reproduction has potential to break laws.
