I mean, Lemmy used to have a big issue with CSAM being spammed by malicious users. Many people believed that it was pro-Reddit trolls, because it started happening right around the same time as the giant API debacle.

By your logic, every single user in instances that got spammed should be banned. Because even if they didn’t see it, or interact with it in any way, they’re still personally responsible for it. After all, personal responsibility doesn’t stop existing in a large group of people.
