I have a couple thoughts on this:
1. The review community, while great, probably represents a tiny percentage of mongers in the NYC area. So these girls could be extremely busy with dudes who don’t even know about these sites. I mongered for years before I even got a hint of these sites existing at all.
2. I see what you’re getting at with the idea of extra credit for writing reviews quickly, but the flaw here is there’s no way to verify the date independently. If I saw a girl a month ago and life got in the way, or I was on the fence about reviewing during that time and finally decided to review her, I’d be tempted to just put the same day or prior day under the date of visit in order to get extra credit.
