To answer your questions:

1. When and where (dulles discovery?) did your CIA  poly take place?

Yes, I took my polygraph at the dulles discovery building here: http://cryptome.org/2013-info/04/ciau-campus/ciau-campus.htm

I went up stairs into the polygraph/pre-employment procedure floor where I signed in and went into the waiting room near those stairs. They played a polygraph introduction video which described the polygraph as a calm and peaceful process. After the video played, that's when all the polygraphers came and took the applicants one by one to be polygraphed.

2. What exactly did they make you confess to? Was it viewing illegal material online, what type of material?

-they made me confess to illegal pornographic material. I was interrogated so intensively that I began having false memories and believing them to be true. The adjudicators also requested a meeting with me as well and they interrogated me even further. The questions they asked me I thought were inappropriate. One adjudicator asked me what ethnicities I had sexual attraction towards.

3. Did you get that letter saying you were denied access to classified info?
Yes, I received a Statement of Reasons about 2 months latter. This exact same one:  http://www.nationalsecuritylaw.org/files/received/CIA/Security_info-contractor_denials_%28ICI%29.pdf


4. Did they make you sign a piece of paper regarding your confession?

Fortunately, not.
