If you're saying that swatting is free speech, then we've pushed the idea of speech beyond all reasonable boundaries and have decided that speech just means that people are free from consequences of their actions.
I haven't seen any news reports which substantiate these claims that Kiwi Farms is a haven of criminality, just allegations in newspapers which are presented as fact. I've seen no way to verify that any of these claims are in fact true, nobody has.
Now, this isn't bigshell's real address. This is a random place from Google Maps and in fact I picked a gap between existing addresses just in case. But tell me, bigshell, if this had been your real address, would you be okay with it?
I'm not thrilled with it but everyone has the full right to copy and share public records and factual information. I'm not taking the morality of said copying or sharing into question here, I just don't see why you can't reproduce public records of factual information.
If I link a social media profile to my real name, or something that identifies me, that's my responsibility.
And a few of these aren't even heinous! If I happen to be self-taught in the law and I am particularly good at giving wise and helpful legal advice, but I am not actually admitted to the bar, nobody is directly hurt by my advice, but society has decided the potential for harm in this situation is high enough that I still shouldn't be allowed to do that.
It's irresponsible, but it's generally protected.
Luckily, Kiwi Farms has always denied having anything to do with swattings, and there has never been anything to substantiate the claim that people are organising swattings on Kiwi Farms. It is (or was) a public website, so if people are really planning this criminal activity in plain sight it should not really be too difficult to provide evidence for this.
The addresses on Kiwi Farms are already public. They're on the White Pages, public voter registries, WHOIS records, legal filings. Do you think that Kiwi Farms not sharing these addresses would somehow prevent a criminal from getting these addresses?
Edit: I completely misread the comment sorry, I thought your statement "swatting is illegal" was implying that Kiwi Farms had been organising swattings, etc. I'm not going to delete this comment though because I like to think its contents make a good point.
