"It’s not just that we don’t trust Mr Zuckerberg with our private info, it’s also that nothing is truly private on FB."
I had a FB page only because some businesses didn't have a website and only used FB. There was nothing on my page- just my name and home city.
After several years of having that page, the one and only time I contacted someone through FB regarding a post they had, FB cut off the message exchange (the other party asked if I could text them a picture of an item I had that they were interested in), denied me access and demanded I send them a scanned copy of my DL to continue. Nope, not happening.
I tried to access my account several times afterwards but I couldn't get on. Apparently my FB page is now gone/deleted. I guess FB didn't like the fact that my page had 0 information, I never contacted anyone (except that one time), had no FB friends, etc.
