Does anyone know what issue of Playboy did Jill from BDJ appear in?

Advertising on this board with your answer would be disrespectful to Jill or anyone else in the same situation. I can assure you that if you see Jill, you will have a time of your life. Only then, in the privacy of yourself and Jill, you can ask her the question you seek.
My answer is simple, you will have a great time, regardless of if she is or is not a playmate or even a penthouse pet.

on hiatus until further notice, possibly permanently.

however, she could get in a lot of trouble with playboy if it is announced via the boards.

good idea to publicly identify a lady.  Messages or reviews containing that sort of info are usually pulled immediately upon notification.  Members who provide sufficient info that could reveal a lady's true identity could be placed under moderation or severe restriction.  The worst offenders could be banned from TER.

A respected LA reviewer, upon his excitement of meeting a Playmate, identified the issue she was in in his review.  I filed a problem report to Staff to try to have that review modified.  Staff chose to pull that review and have that member banned for over a month.  He has to use another id.  His review privilege has yet to be reinstated.  Needless to say, I really owe that guy a big one since I didn't intend to get him into that sort of trouble.

So be careful about discussing this sort of info.

Happy hobbying
