Ask HN: Know of an automated way to pollute the date big tech has on me?

There are people that try to avoid as much as possible sending data to Google / Facebook / other. Using custom built Android, not using the google store or using it on dedicated phones (I know a guy who has a special phone just for the school's whatsapp group), etc.

I am not one of those people. However, I was thinking that instead of not sending data at all maybe I can send them some fake information about that will dilute the profile they have on me.

With Facebook, things seem easy, to like / visit some pages that are not in my interest.

With google / gmail / analytics however, this becomes pretty hard.

Thoughts?
