Possibly. The rails console is a very powerful tool that you can use, but it’s not for the faint of heart. If you haven’t ever used it and want to start, I would recommend setting up a testing site where you can experiment and get to know how it works. The inactive users job is defined here. You could grab/modify what you need from that.
Just noting that the only other trust level it could apply to is TL1 since TL2 has a “Replied to at least 3 different topics” requirement.
