Since two days ago, I noticed that something changed in my bank, with the amount of items. You can guess what happened....
Anyways my main question is:''Can admins or mods see your trade logs?''.

Yes, they can see everyone's trade/drop logs.

They can, but I believe they need a valid reason to do so.
There's logs for almost everything, including stake logs, drop logs and chat logs; all of which can be viewed by a staff member.

If you're suspecting you got hacked I advice you to change your password immidiately and make a ticket in the helpdesk


EDIT: Always have a bank pin, you'd probably have your items as they were if you had one.
It's there for a reason

The items were returned.

Locked.
