I like this suggestion!! It will help if they had a TOS, as we do. We had to agree to a TOS back in November so we could continue using Thumbtack. If it's a rule for us, it should be a rule for "customers" to agree to a TOS. Even though we have no way of knowing if someone is of age, but at least an agreed TOS protects Pros and even Thumbtack, same as if a Pro does wrong by our agreed TOS, that Pro gets punished.
