What’s worse is that YouTube sometimes doesn’t do that, i.e. when you hit back it shows the same list from the cache or something. It gives you hope and makes it worse on those occasions when it does fully refresh on back.

It’s the same story in US and Canada. Illegal, but not really enforced. And when it is enforced the the penalties aren’t strong enough to be a deterrent.

It’s against FTC regulations in the US too. The trick is getting them to enforce it.
