Basically, swatting is an internet fad where anybody can call the SWAT team on a livestreamer/person they don't like. What they'll do is call the cops on a false charge big enough to get the SWAT team. (Please realise that I'm not trying to scare anyone.) Very fortunately, nobody has been hurt yet. These cases are very rare, in fact. But, you may know that these calls cost a LOT of money.
