If you try to access one of the blocked communities from lemmy.world you'll see it's blocked, dude

lemmy.world rule 1:

No illegal content, including sharing copyrighted material

c/piracy@lemmy.dbzer0.com rule 3:

Don’t request or link to specific pirated titles

So c/piracy@lemmy.dbzer0.com doesn't even break that rule. It's for discussion. Unless you take a very broad reading of not allowing the sharing of resources that could be used to pirate copyrighted material, but that's not an issue anywhere else

No illegal content, including sharing copyrighted material without the explicit permission of the owner(s).

The problem is this is still pretty vague. The communities that were blocked weren't sharing copyrighted material, but resources for finding and sharing said material. You might think this is being overly literal but I'm pretty sure it's the same loophole that allows reddit to host r/piracy without getting into legal trouble.

On the other hand, if we take this rule at face value it could be interpreted as not allowing the sharing of any kind of content without the express permission of the creators. This could include photographs, artwork, videos, and maybe more.

So it's not an issue of people being lazy or ignorant, but overly broad/vague rules

Maybe you shouldn’t even have had your account on the largest server to begin with?

Some of us made our accounts on lemmy.world within a week(?) of its creation when it was tiny (June 5 for me). Doesn't stop it from belonging on mildly infuriating
