Distinguish between trespassing-style "you can go there but there might be consequences" and prison-style "you are physically unable to go there"

Currently it's trespassing-style. If you modify your Google client, Google reserves the right to ban you.

With attestation it's prison-style: you can't modify your Google client. If you try, the modified client just won't work. Trying to walk out of the prison wall does not actually put you outside - you just bang into the wall and then you are still inside.
