Why do people here Block their own Profiles?

It's a public site. YOU can make it "safe" if you so desire, by making it private.

I block my profile pretty much because I'm a private person. Some people are on here often enough that if you wanted to get to know them you can read their posts on various threads. People might not want to put themselves out there like that.

I guess OH is not set up where you can have a public profile & a private one.

My profile is 11 years old. When I found OH the internet was a different place and I was a different person. I no longer want to share that information.
