Fair point. To the extent that a ToS is legally binding, then yeah, it should be illegal to make it deceptive. But my understanding is that a lot of what's in a ToS policy has no legal force, and taking steps to regulate certain aspects of a ToS might have the unwanted effect of giving a ToS more legal recognition overall. It is possible to sign over certain rights to a company, but that doesn't mean the company can sue a customer for breaking the ToS when the customer isn't breaking any laws. So, Reddit can write all the menacing emails they like, but if someone feels like posting a bunch of softcore porn in a large subreddit, all Reddit can actually do is ban them, and if they go too hard on the threatening emails, they could get sued for harassment.
