Actually, they can. It is part of the contract that you voluntarily agreed too. It’s not a violation of your rights if you agree to the contract without ambiguities. The ‘no bad review’ was a free speech issue which superseded the contract law. Buying something per terms isn’t.TaC can’t violate your rights you. They could not put in the tac that they have the right to ship you broken goods and you have to accept take it and no refunds. Or how did those “can’t leave us bad review” TOS turn out?
