My friend's art was being sold without his permission. I asked the seller to remove it as it was a breach of copyright infringement. The seller refused to and got extremely defensive about it, claiming that there "was no copyright on the art" so he could "do what he wanted with it". I lost my cool in the message to him and called him a talentless opportunist. They removed my account accusing me of "abusive behaviour" - said nothing about the copyright infringing person. Absolutely and completely outrageous that they would remove the account of someone who was confronting a seller of copyrighted art!
