Sure, though you would you only start to look if you had an initial flag to go off of. If account traders are using 2FA to trade accounts without triggering password/email changes (or delaying changing this information past the wake up date or after a long period of time has passed), they might go undetected. My main point of adding the 2FA flag is that it would prompt those who are looking to go and do so/keep an eye on those accounts.
Just like email and password changes, a 2FA change shouldn't be a "prompt" to investigate an account. Accounts should be investigated if it appears they are involved in some kind of wrongdoing, not because they made a change to their profile.
You've only ever tagged 1 account on suspicion that they were an alt account, accused other accounts as being alts in your posts, but never provided evidence to back any of your claims, so you don't have a whole lot experience in this subject. If you did, you'd realize there's better ways to identify scammers / dishonest accounts.
I disagree. Email and password changes are valid prompts to investigate or keep an eye on an account, as are 2FA changes, as they show that a change has been made to an account. If account trading is something that people get negative trust feedback over, then it's valid. If it doesn't effect the trust level of a person, or if that's what you believe, then sure, your statement is somewhat valid - though that's not the reality from what I've seen.
To say I do not know how to spot them just because I haven't (yet) posted about them or use my (useless) tag for my observations is a poor assumption. I've already got proof of a merit source farming accounts with hard evidence that I'm posting soon, which ties together a ring of 10+ accounts that have shared thousands, maybe tens of thousands of merit with each other, as well as farmed tens of accounts, as well as progressively doing research on other members and casinos which I have mentioned before too. You're welcome to disbelieve until they're posted, that's your right, I am taking my time as I do not spend all of my time on this forum, do not have much time in general and due to the delicate nature of the situation (involving those with high merit and trust in the forum) I am not in a rush to post these things until it is impossible to refute.
When they allow account sales, though discouraged, then why should he add this kind of stuff to prevent account trading? Because whatever you add, it doesn't prevent account sales. You can't detect true account trading through email or password change. Who often visits mod logs to identify email password changes? And how it does make sure the account changes hands.
I am always against account trading; I am not encouraging them but expressing the reality. Account traders will find a new way to trade accounts, whatever you implement. We just need to notice any suspicious activities from email password-changed accounts. I don't believe the account buyer will leave the email password as it is since 2FA could be changed or reset through these.
The password/email change is a marker on when ownership can change, and differences in posts before and after that point can help to identify and prove that. Despite all of what you and others have said, and no matter how members want to twist the subject, the fact is that without 2FA being added to the seclog, it's a method that account farmers and traders can exploit to avoid detection. In a community without corruption, and in a community where account farming and trading are genuinely frowned upon, I see no reason for the information to not be added to the seclog, considering that password and email changes are already recorded.
