I'm new to this and this is a serious question so please don't assume I'm accusing anyone of anything but if I bought a Facebook account from someone and set up my credit card on that account in order to buy ads and at some point in the future the account gets locked and requires a government ID to verify the account, how do I make sure that the person I bought the account from doesn't now log back into the account, verify the account with a government ID and then use my credit card to buy ads for themselves or worse? Should I change the password and/or immediately after buying one of these accounts (but would that bring up red flags to Facebook)? Should I just cancel my credit card if I get locked out to make sure this scenario doesn't happen?
