What about art commissions that are taken through this site? Pre-paying is usually a must with those due to common scammers and issues of "I don't want it anymore" even after you spent days working on a piece of art for someone. If someone says that will pay you and they don't, is that against site rules, and will they get punished? What if it is for REAL money? You can't force someone to pay money, especially if they don't have it. Should I start handling commissions off-site then? I don't want to break rules, but I also want to protect my work and my time. ;-;
