then why do i see his profile uid in mod-log ? cause it displays the auto ban's, done by mods .
That was something new, didn't know bans were visible as well.
Well thanks for the info
again , it is not something new . I assume your mentor never addressed that deep ...lol (kidding).
edit :- you can pm me if you need some deep info ever..

Autoban is permanent, unless manually removed/modified. Nuke bans and removes all of a user's posts (spambots usually). Manually applied bans won't show up in the modlog, those are usually temporary, but not always.
it will be a mystery now, until badbear clear's that if it was his first ban or not.
The original user might have been banned year's ago or mod's didn't checked the list and took sudden action on all users in the list.
