> For instance, if a user were to say something egregious like "Empire Strikes Back is bad", what is preventing especially enthusiastic fans from labeling them with having uploaded child abuse content. Presumably that would be a good way to get that user banned from most popular servers. Suppose @alice:example.com says “Empire Strikes Back is bad”, and @bob:example.org labels Alice with “uploaded child abuse”. The label attached to @alice:example.com is not “uploaded child abuse” but “uploaded child abuse, according to @bob:example.org”. Perhaps @charlie:example.net discovers this and labels Bob with “false moderator”. Maybe @drew:example.horse labels Bob with “false moderator” and Charlie with “true moderator”. Each server can decide whether they trust Bob, Charlie and/or Drew. Anyone who cares enough can check whether Bob's assertion about Alice was correct, and so they can learn whether to trust Charlie and Drew. This is similar to how blocking works on [scuttlebutt](https://ssb.nz https://ssb.nz), which is subjective by design — if I can see that a few people I trust have blocked a certain identity, and they've left a message saying why, I can choose to trust them and block that identity myself.
