"Everybody lies". Even if the majority of people's history and proclivities are considered "vanilla", those individuals themselves don't want that information being made public, would likely feel some sense of shame if the information got out, and want to avoid any situation where they would be judged or teased. Even if that content is considered relatively tame by a tolerant society.

Lot of people look boring in public but really aren't in private.

Also, pretty much everyone is guilty of, at the very very least, numerous traffic violations.

> Lot of people look boring in public but really aren't in private.

Of course.

I am referring to the people who are boring in private, clearly.

Even the most boring person has information they want to keep secret. Banking activity is the obvious one.

There's a huge difference between secret because it's embarrassing and secret because it's a pain to deal with fraud. Many of them would have no problem turning all of that banking info over to "the authorities" :)

i can definitely think of a few things that can come from purchase history that could end careers, relationships or families:

1) Having homophobic parents and buying anything supporting a “non-traditional lifestyle” (like books from a particular vendor)

2) Having liberal parents and buying say a firearm

3) An unfaithful spouse supporting another relationship (remember Ashley Madison?)

4) Being a well known promoter of a particular brand when buying from another for personal use

>Do not count on being able to embarrass the enemy

Why are you making folks that disagree with you "the enemy?"

Just because some doesn't agree with you about a particular issue doesn't mean they are your enemy.

They just disagree with you on a particular issue. Assuming they live in the same culture, it's likely that they agree with you on more stuff than they disagree.
