First I thought that this is a ridiculous reason to send SWAT after someone (not that there is a good reason to send police on a fake call) but then I realised that this is actually the best motive for SWAT "trolling."
After all if you do it to your neighbour or ex or someone you know in real life they might be able to trace you. Doing it to someone you just met on net (and bothering to hunt down their actual ID and apartment.) makes it harder to trace the culprit.
Anyway, this is horrible, those cops could be needed on a real emergency call.
