The problem with terms of service is not that you can't read them or that you don't. The problem is that even if you do you're going to have to come back to reading them every couple of weeks in case they suddenly change and pull out the rug from under you.

Terms of service from the time of signing up should be binding and a service should be suspended until you accept new terms of service should they change. That way at least you'd have a loud and clear warning.
