At least one, however, /r/FoxesInSnow, was not inactive. Not when they removed it, at least. How do I know this? Because just 2 months ago, powermod Iangator requested it so he could nuke it.

Thus being active then, for him to nuke it, it should not have met the inactivity criteria. The only explanation is that the admins manually removed it out of personal spite for me, and this powermod was probably in on it as an excuse to make it private. None of the subreddits I nuked myself were removed, and they have been shut down for far longer, private with no mods. And I think that's the key here, the admins don't know to remove them since I'm not a mod there, meaning they went through my mod list and removed as many as they could on it without raising suspicions.
The fact that they've still got such a huge grudge against me after I've not touched their site for over a year now is just unbelievable.
Edit: It's almost 100% confirmed now because they banned one of them right before Iangator's request too: https://www.reddit.com/r/retcons
Edit 2: And now there are a ton spammers asking for upvotes in another one of my old subs: https://www.reddit.com/r/DefaultModsSucks/
They started spamming at the exact same time as my other subs went down, and none of the spammers are banned. Coincidence? I think not!
