What would they achieve By doing this? Sending hit mob around to someone home, getting them badly hurt?Theres a reason why courts won't allow IP address (this lie that influencers spread explained here) to be used as proof of who accessed a website.
Anything I have seen on here as as been stuff that you can access publicly without even signing up or password. Perhaps if they didn't post so much of their private life on a work page then no one could comment.
I wouldn't go to work and chat all day about all the amazing things or holidays I have had or intend to go on. Apart from close work friends I wouldnt say alot about my home life because it's work. They should make a point of saying work page and keep it at that.
