'The internet is rife with online communities where users can go and share Zoom conference codes and request that pranksters connect and hurl insults, play pornographic material, or make death threats against other participants -- in a practice called Zoom-bombing or a Zoom raid. From a report:

ZDNet began tracking the tactic since mid-March when the term was first coined following a TechCrunch article. Ever since then, Zoom-bombing incidents have increased, as articles in major news outlets like the New York Times and the BBC have made the practice a favorite pastime for all the teenagers stuck in their homes during the current coronavirus (COVID-19) quarantines. From a niche prank that started on a derelict Discord channel, Zoom-bombing has now spread to enormous proportions -- being so rampant these days that the FBI sent a nationwide alert last week, urging companies, schools, and universities to take steps to secure their Zoom channels. But as Zoom-bombing became more popular, more pranksters wanted to join on the fun, and more users wanted their friends' Zoom meetings disrupted. And as the old saying goes; where there's a demand, there's always a supply. Over the course of the past week, the number of places on the public internet where you can request a zoom raid from a gang of bored teenagers has exploded.'
