Swatting is not even being done by just kids--there was this case where a /British/ guy from overseas got a man swatted and shot by police in Kansas: https://tinyurl.com/kty6wof
And it's not just kids doing this, I don't think--they did it to Calebhart42 on twitch and he's not even that popular, by Twitch standards--he's just some dude who speedruns megaman x and final fantasy. What I think this is like tombstone mentality where nothing got done about it till people started dying. And lets face it, not to say anything bad about police, but you're going to eventually run into that one cop with the itchy trigger finger, like that one in Arizona: https://tinyurl.com/y7u4bc52 (that was the guy who had 'you're fucked' written on the side of his AR-15, which cops carry in AZ because I dunno, the south.)
We basically live in an age where people can reach right out over the internet to kill you. Probably good incentive to not put your personal details online.
