The title is misleading - it sounds like they specifically went there to harass employees by filming them, and Meta took down the videos for harassment, like they routinely do if this is reported on their platforms. I'm really not sure what the issue is.
TBH this is tamer than 99% of the content published by Creeper Glasses users that Meta itself relentlessly shows to me.
Having watched the video, this hardly meets the standard of 'harassment' or bullying. This is a vox pop, that people can (and do) walk away from.
