Completely agree. This is similar to shared host that offer unlimited space. For those using a lot of share/cpu, they'll get a friendly reminder to upgrade, then a notice that they can't continue supporting them as a client with their current plan.

The Flickr Pro account 24.95/yr for "unlimited storage" was an easy purchase. When you login with your Pro account you are suggested to downgrade to the new 1TB (ad) account.

For 49.99/yr I have to ask myself, do I really need this ? what are my other options.
