thanks for the link ness - I'd just noticed the same thing.. I need a reporter badly in Strangetown - I didn't add a sub-hood an there isn't one! I tried spawn reporter on the Badge juicer last night - no reporter in several hours play.
If you mean you didn't add the OFB sub-hood, it isn't necessary to have a Reporter. I've not added the OFB sub-hood to any of my neighborhoods and the last time I played the reporter showed up on the home-business lot I have in a custom neighborhood. It took several in-game days before he dropped by (or revealed himself at least); I believe the reporter is a pseudo-random event.
Note that the reporter will not reveal him/herself unless he or she accumulates sufficient Loyalty points to gain (or lose) a star, at which point she "publishes" her review. As I understand it, the reporter will only hang around for five hours at a time; If she accumulates 80 points (out of 100) in that time, she won't file a review, but the next time she comes by she will only need 20 more points to write the review. I actually didn't notice the reporter on my lot until he told me he liked the venue—I didn't hear the pencil sound or notice him taking notes.
