I'm a current mod of r/motocross (30k subs) and I have the magazine here at Motocross@kbin.social. It's not affiliated, but the other (active) mod is likely leaving Reddit as well, no word on landing zone though. It'll be a dead modded sub likely by tomorrow once I and the other guy leave.
I also created ElderScrollsOnline@kbin.social but I wasn't affiliated with the sub reddit beyond being a long-time user.
I also have the @fedia.io versions because I wasn't sure which instance I'd be on. Still not sure, but I imagine the kbin instance will hold the magazines and I'll just figure out which instance I'm going to mod from long-term. If that's even possible.
