Or how about a more general law, saying whichever medium you used to subscribe must also be available for cancellation? That way we also cover the inverse: tricking old people into signing up for someone via phone, and requiring cancellation online (if that is allowed, I'm not sure).

How can I vote for this? Is there such a bill we can pay --er..encourage congresspeople to endorse?

Ha ha. I'm English, so I've never been entirely sure how American lobbying works, but ever since I learned of it I've thought it could be an idea to set up a website (lobby.com) where people could propose laws and people could pledge donations to get laws enacted that they like the look of. If a particular law gets enough pledges to reach a particular financial threshold then the money is deducted from the accounts and a lobbying process is started to get the law enacted.

Anyone else think this could work?

[edit: forgot a word]

When this topic has come up here before, people have mentioned jurisdictions in Europe that do have such a legal rule.
