I don’t get it, can someone explain?

I am surprised this happened, it’s the first case of anything like this that I have heard of. Do you know of any other cases?

I don’t know the details but wasn’t one of the instances that Lemmy World defederated recently one that contained lots of toxic shit (racism, trolling and other not cool content)? So it’s not unlikely someone from there decided to just destroy things for others. Maybe even an operator since the person(s) obviously has knowledge of how Lemmy works.
