reocities.com got banned for no reason that I can think of, never bothered to try to engage google on this because it is as good as pointless. Google just simply doesn't care, as long as more people are signing up than they are cancelling they can keep the ship afloat. On the off-chance that you're trying to social engineer them they apparently can't take the risk to re-enable an account.

So, I've taken the attitude that google adsense is to be avoided like the plague for anything approaching a business. It's found money if you can get it, and if you can't that shouldn't be a factor in your business plan at all.
