I crowdsourced a logo design on Crowdspring, which supposedly had procedures in place to prevent plagarism. Resulting from posting a new project here, someone who looked was able to tell my logo had been stolen from a company halfway across the world from me- local to this user, but unknown to me. I wouldn't have known & could have run into legal issues down the road had I kept using it. Unfortunately Crowdspring ruled it wasn't a refundable issue, so I lost around ~$4k on a design I can't trademark. Would be nice to be able to do something about that, but I currently lack the resources necessary to persue it legally.
