Can't speak to Burggit's place in the saga, but its widely speculated the vlemmy admin found some CSAM in the data storage and shut the whole thing down so as not to be further legally liabile for illegal activity on the server. I've seen some people saying admins don't have to worry about that because of this section of this code of that countries legal doctrine or whatever, but the reality a lot of us face is that law enforcement and prosecutors don't care how the CSAM got there, or if you knew about it, because its your burden of proof to prove them wrong about that, and they just have to make jurors who don't know how the tech works think its your hardware, your hosted service, and therefore, your CSAM. The consequences of mishandling or not documenting your actions in regards to CSAM are incredibly dire. You could see yourself permanently sent to prison, and if not, upon your release permanently ostracized in very complex ways that could render you permanently homeless.

I like... Don't understand the stance that Ruud or VLemmy are overreacting at all. Those are the stakes in some places, including where the majority of instances are hosted. It gives me the read some people don't care that the admins are just people like you and me hosting these services to make good communities happen. The expectation for some people seems to be just like... "Keep the service up no matter what. I want to view content. if it becomes impossible to host, just sail out into international water. The content must flow"

Though I haven't confirmed it (nor would I want to at this point), from my recollection of events, some community from burggit.moe was allegedly the source instance of the problematic images that were thought to have taken vlemmy.net down, which was reportedly some sexual depiction of young fictional cartoon/animal characters. This might not be illegal in some places but it definitely is in Ireland, so the server owner was notified as such and had most of their online accounts removed.
