So it's good for someone to create account with valid email address so that if the email is been tampered a notification will be received.
like that. member sign up with a random email. then they replace it with a valid email.
but for the case of the bounty hunter account, it doesn't seem too much of a problem.
We don't know how hackers started taking over other people's accounts. but if that happens, I think the forum has provided a rule for us to reclaim our hacked account.
The problem is, as @Darker45 said, most hackers target accounts that have been inactive for a long time. if the email used is linked to a mobile device, the owner may get a notification. but if you have lost access to email, that will make it difficult.
