I got off years ago. Big data doesn't know who I am! I have over 500 google emails addresses from different IP's and I use them to get accounts for images, videos, vpn's, steemit accounts.
I love filling their data centers with trash. I have a drawer full of mobile cellular phone chips - hahaha.
I either flood them with bad info or don't give them any.
That's certainly one way to keep your identity off the grid.
