So you've deleted everything? The profile looks clean now.
I also want to know is it worth it for that user to get a temporary ban or permanent ban once the main purpose of posting the link is known?
Everything I deemed as advertising, which was everything as the link was always included. Plus, they didn't have many if any posts actually interacting after posting the threads. I can only nuke, and therefore deciding against that, since I thought a temporary ban would likely be better. That's up to the globals/admins though.
