I have a minimal FB profile but only wish I had put in entirely false information to begin with.
Everyone should “poison” their data, but if this becomes a big enough movement as you suggest with a “one-click” way to do it - it will also “poison the well”.
Facebook makes it’s money by selling targeted ads to reach specific people. The entire foundation of that concept is that people provide truthful information - if they lie and make up crap then the value of what they have to sell is diminished. Imagine what would happen if you were paying say $500 a month for FB ads to reach people within 30 miles of your store, only to discover that half of the “people” you were paying to have your ads delivered to lived all over the country and just picked your town at random? You’d instantly want $250 back, at the very least!
If enough people poison the well, it could put Facebook out of business! Their entire business model would be damaged beyond repair.
My entire FB thing was fake.
Funny 2 days after all this crap started they told me it was suspended unless I could prove who I said I was.
Buh Bye FB till I can build a new Fake account
So, it's pretty accurate, unless you happen to specify an attribute that's a proclivity of an extremely paranoid computer user spoofing, etc.
Yes, it's irksome. I recently inherited an older iPad, and didn't subscribed to any Apple offerings (limiting my access to apps, among other things), but I still get ads targeting my location. I reset the ad id every now and then, too.
