I've asked on several occasions if Vod has any way to be able to detect OTP changes, though so far there hasn't been any feedback.
If possible, theymos should grant the ability for bpip.org to detect changes to 2FA/OTP on an account, to eliminate this new possibility for account traders.
It even with the 2FA granting users account access by the OTP settings/recommendation, it will still go very dark to have significant program that is to tell when an account is being handed over to a third party to be a sold account because even the rightful owner could decide to change their contact informations to grip the OTP module.
Even when get to track the accounts IP, it is still unreliable to detect when someone else is in charge of someones account.
So, the only remedy to this is the need for Kyc verification during account registration and when logging on to a different device which I am believe it will be Impossible because the bitcointalk platform is embedded on keeping members reality identify secured and unrevelable.
So, the only means to catch this up is by having an efficient techniques of identifying when a posting model is changed from the previous posts.
This should as well be in the case of hacked accounts also and not just targeting on those dealing to sells of already built accounts .
