Personal experience. I had a very high clearance at one time.
Heck, I had a security clearance many years ago, and I had to stop dating someone from New Zealand. I should say, that if I wanted to go out with him I had to go through a bunch of loopholes and paperwork. I had just met the guy, and wasn't that interested. It wasn't worth the hassle.
