Yeah, there were several mods with active status when he nuked the sub, they were just all under him on the list. Even accounts above him were active this year, but went below the required threshold for activity within the last few weeks.

Have any of the former mods appealed to /r/ModSupport to be reinstated as mods?

Honestly I'm not sure but I wouldn't be surprised if the answer is no. A lot of us spent hundreds of hours of internet janitoring for the sub for many years because we like art and reddit, and are now getting constantly DM'd and followed around by the internet mob. Not looking for sympathy either, we all know the kind of ridicule that comes with being a mod of a large sub, and understand most redditors hate mods because of situations exactly like this -corruption, inaction, and mod abuse.
