They had a right to do it. It's just annoying they didn't have a method in place to go after those who scammed everyone.
agreed this just sucks.The keys being revoked won't effect them at all in most cases, the only people this hurts are the ones who bought the keys, the sellers are laughing all the way to the bank.
They were legit codes, I paid 35 For mine, I'm hoping eBay refunds me but I've five this dozens of time and never got revoked so it sucks. I understand why they did it but legit people got screwed and Its a shame people are defending that.Buy games legit keep legit games. Its simple really.
