This user has been active on Lifehacks recently, even though he's currently suspended network-wide until June 14th (one month suspension started on May 15th).
He was unsuspended manually by a moderator on Lifehacks.
This is... probably intentional? The fact that something like this is possible in the first place may or may not be harmful, depending on the user and the site in question.
We may revisit network suspensions to lock them down further, but honestly, I'm not too worried about it. It's rare for a "real" user to get suspended network-wide, and if a particular community still feels they're welcome there... fine.
I unsuspended the user
This was a test to see if it was possible to unsuspend a network-wide suspended user on a single site. I'm glad to find out this is by design rather than otherwise.
Due to the nature of their original suspension -- which is not mine to discuss -- I have resuspended them on Lifehacks to end at the same time (approx) as their network-wide suspension.
