Can you please answer, what kind of accounts are these? I trust they are quality but this sounds like hacked accounts... here's why:
- If these are farmed accounts then you would have the username/password and it wouldn't matter if you got logged out
- If these are rental accounts then you should be paying the real person money per month, and if they log out you contact them and make them log back in or you cancel the rentals contract
If these accounts are not farmed, and they're not real rentals, what are these? Why is your service unable to stop the user from logging out? I've never seen any kind of FB ad accounts setup where if the FB profile user logs out of their account, then you can never get back in. Well... unless the accounts are hacked, then yeah that'd make sense.
