It's antagonistic and obviously misleading to state that a person has given explicit permission to a company without any further explanation when the reality you're basing that on is that the permission was in the wording of a contract that person clicked "agree" on.

You may insist all day that this person was irresponsible in examining the contract, which I will also disagree with, but claiming that they have given explicit permission is a lie on your part, and I would have a hard time believing that you don't know that.
