I think he will be my first block as well lol

Wait I can block instances from showing up on my Lemmy.world homepage without having to ask Lemmy.world to block it? Is this a Lemmy specific feature? Or is this a common Fediverse feature? Will this also block that instance from showing up on my search? As an example: If I search for the abbreviation of CyberPunk and the "illegal CP" shows up on my search, I can also block that instance from ever showing up on my search?

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 thought about not having that kind of content on the internet. Well... there is but as you said it is either raided by the host (be it a company or a country) or we don't really have access to it because it does not show up on Google so we have no way of knowing it even exist unless we look for it. But, as my experience with Lemmy is that my homepage is filled with many posts from different instances that I never knew existed. What if an instance sharing "bad content" shows up on my homepage? What is the next step that I can take?

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.
