Long story short, you can pretend to be anyone to post anything on their page. And if that doesn't sound anti cx enough to them, they will modify and edit your original post to gain popularity.
I pretended to be an Emirates Crew and submitted my post as, "cx cabin crew should stop complaining cos as an Emirates Crew, we only get 24 hours layover average in almost every port".. Then unsurprisingly, my published post became I'm an Emirates Crew and I support the welfare of cx cabin crew, keep fighting. What kind of BS!
