From a 2002 article about the AutoFocus film:

"On one side is Robert, 51, one of three children Crane had with his first wife, Anne. A journalist, he was paid $20,000 to be an adviser on the movie and has a small (if ironic) part as an interviewer for a Christian publication who quizzes the TV celebrity on his tips for a happy marriage.

On the other side is Scotty, 31, Crane's son with second wife, Patricia, who was Hilda on Hogan's Heroes. His mother, who was separated from but never divorced from his dad, is executor of the estate and inherited proceeds from reruns. She also owns thousands of photos and tapes that document more than two decades of Crane's sexual encounters, a selection of which forms the centerpiece of Scotty's infamous Web site shrine, bobcrane.com."

I think the bobcrane.com site no longer has that material though. But here's another comment about that site back when it was different:

"The reason Scotty Crane is making this material public is so people can finally see for themselves what went on during the making of the photos and videos. Many rumours have stated that there were homosexual acts and dungeons involved, and there is no truth to that. Now people can see the truth. There is a family section of the site and also an adult section with XXX video clips and photos of Bob. You can also buy collectables at the site, too. This site was done by Scotty, NOT Patricia (even though some people like to make it seem like she is behind it). If you heard Scotty mention that site, you may wanna visit his radio show website Shaken, Not Stirred too."

(Does Scott Crane still live in Seattle?)
