"Zoombombing" has become an issue for those using the software to connect to long-distance meetings.
It happened recently to a prominent Rochester musician in front of a worldwide audience.
Judah Sealy, who is also a church music director and school music teacher, joined a London Radio host for DJ Saphire's Smooth Jazz Lounge program last week. An hour into the web interview, racist trolls broke into the show.
They spewed a stream of epithets, including a very painful racial slur. One person asked if it was a Ku Klux Klan meeting.
"That was the last thing I saw, the crosses and the KKK and the masked person. That's the image that stayed with me," said Sealy.
"It was,`we gotta get outta here.'"
The Zoombombed show stunned him. He said he even felt responsible for being on the show.
Sealy wants to move on — but he's talking now because he wants people to know this happens.
"You're a respected musician, no one can think that way about you. Or you're a respected doctor, a respected lawyer, or you're a news anchor, that can't happen to you. It can happen to anyone," Sealy said. "That's not cool. What can we do to fix it? If we start there, I think we can move forward."
Sealy was set to perform at the Rochester Jazz Festival last month before it was postponed. He has a new album out in August.
When it comes to the students Sealy teachers at Rochester Prep Elementary in the fall, he says he'll tell them, "you can't let it slow you down."
As far as the internet trolls who Zoombombed the jazz program are concerned — some of the voices sounded American. Others, British. They don't know who it was.
Sealy says as long as people can develop compassion for people who experience what he did, we're headed in the right direction.
