Which is the the scenario I talked about of having a “blacklist”. You saind on step 2 to “warn other instance admins”. As I see it I would have to first, know who are the admins of every popular instance, then I have to manually warn them one by one, and that is assuming I did not forget any. And we are not even talking about other Services like Mastodon that could communicate with this “illegal content” will I have to warn the admins of the instances there as well? I think what I’m asking is: Is there a way to easily do this? A report system not for a local community, but for the Fediverse itself? And on step 3 you said: “report to the police”. What would my local police be able to do with a server running on a random country anywhere in the world?

Yeah, I totally understand that. As a personal example: I’m against its civil usage of firearms, if someone is using the Fediverse to sell them, who am I to say that that is illegal? It might be illegal where I live, but maybe it is legal where they live, we can’t really be judges on these kind of topics. I used the term “illegal” because I couldn’t find a better term to describe those kind of subjects that (hopefully) 99.99% of people would totally NOT be okay with it showing up on their homepage, like the two examples I provided. What is the plan for that?

If I understood your joke correctly, then you may be confusing “bipolar” with “multiple personality disorder”. They are entirely separate things.

I’m kind of new to the Fediverse, but since their username does not have a “@instance-name” it means he is on the same one as yours, right? Which would be “lemmy.world”.
