Shira Goodman, regional director for the ADL in Philadelphia, says some zoombombers are just people who want to be disruptive.
"But there's also a more malicious side. We're seeing people using it and interrupting meetings, showing Nazi symbols, saying racist things, anti-Semitic things," she said. "Domestic extremists are talking about it, so they're manipulating this technology to kind of spew hate and sow division at a time when people are really seeking ways to be connected."
There are some simple ways people can protect their meetings and virtual hangouts from being hijacked. Goodman says they've created a list of guidelines.
"Don't make your meetings public. Instead make them password-protected," she said. "Avoid sharing the link to your meetings on public platforms like Twitter and Facebook. And only allow the host of the meeting to share their screen."
The ADL has this safety checklist:
"I think we’re seeing in so many ways the best of America right now — creative ways people are coming together, helping their neighbors, looking out for each other — and we just have to fight back against these impulses of those people who would seek to divide us, who really are trying to promote hate and sow division. We have to stand together and fight against that," Goodman said.
Anyone who is zoombombed is encouraged to file a report on the ADL website.
