Citation highly needed. I'm close to quite a few people who run larger instances than that, including my own, and none of them have ever told me about getting subpoenaed. That's exactly the kind of war story we'd tell each other, too.
I've seen no evidence that running a fediverse server is nearly so legally fraught.
I'll go looking for the citation and it may take a couple hours but I'll point out that FWIW my info is drawn from some academic surveying vBulletin and Xenforo site owners in the 2010s so I wouldn't be surprised if they aren't applicable anymore.
No problem. I thought that seemed on the high side but didn’t have any stats to counter with. Which paper does 430k come from? I’d like to squirrel that away for later.
