Definitely do not even give them a thought. The worst scam I've ever seen. Liars and con artists. Sure, they'll have some tiny bit in their T&C about automatically "upgrading" your membership if you click a few 'upgrade links', but they don't notify you in any way when this happens. And in a years time, after you've already cancelled the initial membership and you think it's all finished with, you'll get charged out of the blue for a service you didn't even know you signed up for. And then cancelling all that is just a nightmare. Not to mention the terrible quality of videos and the stealing of other people's content to sell on.
