So (not to) fun fact: Keffals, who was targeted by KiwiFarms for being trans (yes that’s all) and got Swatted. She then went to stay with another streamer (EllenFromNowOn) in Northern Ireland. Just for information sake, Northern Ireland is still a bit rocky security wise, Police there still carry guns on the regular. So when she went there, Ellen called up the police and explained the situation to them (they had never heard of Swatting weirdly enough).
Sure enough, someone found her flat, posted her address (with a message referencing a Unionist Slogan, Ellen was from the Catholic Community), and sure enough, the police came. Instead of raiding her all guns blasing (which they normally would) they saw the warning, knocked on the door, saw nothing was wrong, called off the squaddies, and came in to basically make sure everything was okay.
Bare in mind, this was in Northern Ireland, a place where the Police still drive Armored cars and have regular riots, and they handled this better than the Police in London, Ontario.
