Yup. Happened to me months ago, when the credit card failed to renew and it switched back to free, the allow training setting also got activated. Cheeky bastards. I guess they just vacuumed all my past convos, and you don't have anyone to complain to!

Since I still need to use that account with Plus, I added a new card, flipped the switch back to no training, and submitted that thing on the privacy page which is a bit more formal. Probably should have signed up for a business account.
