The very fact that you own/play video games or the type of games you play.
For example, if you're a vocal opposer of violence in video games in your local community, you might not want others to find out you have a GOG account with Doom BFG + Quake.
Or you might not want your girlfriend or family to find out you spent 2k $ on video games last year.

There can be some legit reasons.

god I hope you're joking. XD

You are the best employee we have here at the company, Johnson. In the third quarter alone you singlehandedly quadrupled our normal profit. Unfortunately for you, it has come to our attention that you own a copy of HuniePop. You have thirty minutes to clean our your desk, turn in your ID badge, and get out of the building. If that company car isn't returned by the end of the day we will consider it stolen. Oh, and you better go get your cancer stricken son out of the hospital because we are revoking all medical benefits immediately.

Or those smexy games you bought. We know you play Lula... >.>

But it's a business sim, it's practically an educational tool!

But we're running a church here, not a porn empire!

There's a difference?

Umm yes... unless your church is the Blessed Huniepop Virgin of Lula.

How do you get a nun pregnant?

Dress her up as a choir boy.

That was good, LOL

Make that two.
