According to BPIP, the email wasn't changed, it means the person still has an access to his email. It doesn't look like got hacked since the original owner should been able to recover the account.
Or the account was hacked way before BPIP came into existence. It's possible, given that the acocunt is very old
Assuming the account was bought by someone, that mean the owner is the same who control the other two accounts, isn't?
still two possibilities here as I stated above
do you think the two accounts are deserved to be painted too?
Of course, Why not?
