On bpip.org, it will remain there.
Yeah we can easily check under meta log for any user there whether he has waked up from inactivity or password reset that have data saved there for all the time.
Not really.
Visit
Security log and see how many users have changed/reset their password recently. How many of them have been accused of account changing hands?
As long as there's nothing suspicious (like posting style being changed), no one is accused of account changing hands, just because of the password being changed.
Right many users change password for security reasons but that doesn't imply anything suspicious until they have waked up from long period of inactivity and start posting with changed style or something else that could create doubts on them.
