It was a rogue mod u/NiceBaitMate
u/eigh7 has been adding a lot of mods to placate the admins as they ramp up Anti-Evil Operation's censorship; one of them was a bad apple.
I have reverted it.
I added four new mods and one of them turned out to be troll. Thanks for fixing everything.
Here is what happened. This sub was practically unmoderated for a year. You can check the posting history of the top mods and see that almost all of them have been inactive for years.
Every time Reddit censors something this sub naturally gets a lot of traffic. This is exactly what happened a couple of days ago. I was afraid this sub would also get banned if left unmoded so I loged into my account and added new mods to help out.
I did that by going through this subs history and picked about ten users with older reddit accounts who have recently been active here. Four of them said yes so I added FreeSpeechWarrior, GuardiaNES, Farnsworth_The_Dog and NiceBaitMate.
The last one turned out to be a doughnut, did some foolish things and finally deleted their account. It should all be back to normal now.
Looks like they temporarily disabled new registrations. They do that whenever they get a big influx of new users. Check back in a couple of days.
I will add a couple of new mods ASAP.
