I have seen many Bitcointalk accounts getting compromised over the years and those accounts are then used for malicious activities. I believe a lot of that could be avoided if Bitcointalk added support for members to add an additional factor of authentication in from of Google Authenticator or some other way.
If you don't know there have been several hacks of the BTT database, and the biggest one happened in 2015 - and everyone was warned to change their passwords, and also not to use a security question for possible account recovery (because that options can very easily be abused). Unfortunately, many have ignored this warning, and have not even signed any of their coin addresses, which would allow them to regain possession of their account.
Although it can happen to anyone to be hacked in some way, it still very rarely happens to those users who take care of security when it comes to the forum and the internet in general. If the user sets the appropriate unique password for the forum account, and if he uses e-mail that is also exclusively related to the forum with also a unique password - then there are only two possibilities for someone to hack his account.
- if someone comes into physical possession of a password that is written on a piece of paper, or is stored on a computer in unencrypted form.
- if the user's computer is infected with a keylogger or remove access trojan.
I have nothing against extra security, but if someone is careless then even 2FA will not help them.
