My recollection, FWIW, is that by the time they belatedly decided to make an effort to regulate entrance like this, the writing was on the wall and the original vibe of the club had been lost. Frank Broughton writes about this eloquently in his "Death of the Sound Factory" article on djhistory.com. The first time I got asked was sometime in early 94 when I took two women friends that were visiting from London, it was simply along the lines of "do you know this is a gay club." I had never been asked, or witnessed anyone else being asked, prior to that. Until stories began appearing in the media, there simply weren't a lot of straight people trying to get in, plus there was also the dangerous reputation (there were still occasional fights among the Tracks crowd as of early 92).
