I tried sitting on a ball at home some time ago, but after a couple of hours on it, my back is on fire. It did not go away after about a week of trying, so I gave up.
I once tried to remove my Facebook account. I found a form (via Google) for this purpose and filled it out. However I got an error reply via email which looked like the email sent by the SMTP form was not being accepted by some Facebook server. I complained of this via support, and within one day they removed my account.
I sort of liked that system. There were almost no vanity/"spam" domains in the TLD.
