I do feel certain Robin has nothing to do with any anon posting, though. Since the board remains ad free, she is paying money & evidently surfaced just to clean up the spam.
Here is an old, old post of hers, but it shows her moderation style:
She did ask, seveal years ago, if anyone was interested in taking over moderating. I was already more of a lurker, but my understanding is that although some posters expressed an interest, there was never any response or follow up & emails were bouncing back.
HTH helps some, from an old timer.
Good luck to you!
