That story doesn't play. There is no way they could "see" what a student was googling while in a remote session. Zoom doesn't support that. Teams doesn't support that. Any third party monitoring software would be ridiculously expensive and I can't imagine individual teachers even having access to it, regardless.What predatory behaviors? If they see students who are active on trans and LGBTQ sites and they approach them how is that predatory?
The teacher said it was a joke taken out of context. It's a dumb as hell joke but it's the only explanation that makes sense because the story as told is unpossible.
