Inappropriate Computer Postings

I have been in the same job GSA contractor for 7years, 4 months. I just finished an SF85P in person interview for reinvestigation. Previous background was SF85. Anyway I was fired from a job in June 2006 for posting inappropriate things on a work computer blog. Innuendo, silly, immature things, nothing threatening. Someone got offended and I was fired. During my interview today the “investigator” seemed to pry as to why I was fired. I told them what I remembered. The SF85-P requested 7 years of information, this firing was outside 7 years. Am I going to lose my current job of 7 years plus because of something that occurred 8 years ago plus.
