This is really old. SWAT'ing died down a lot once some of the perpetrators started getting caught and arrested. One was even arrested in the UK for SWAT'ing a streamer in the US. Surprisingly, trolling people by putting their lives in danger isn't as fun when you face real prison time. Fancy that.
Also, as others have said, there is no hacking involved here. Doxing and social engineering, yes. Hacking, no.
