Wowie --
I agree that JAG declined in value after it became a pay site, but I am still having a hard time following some of your logic.
As Justme states above, comparing UG and JAG is like comparing apples and oranges. They are geared toward providing two completely different services. A comparison of UG and TBD would be a much better fit in my view.
At any rate, irrespective of whether you prefer UG, TBD, EA, *** or JAG, that's your business, but I really don't see how the intant access feature is a problem. Indeed, it is actually a benefit for JAG members as it brings new members/ideas/reviews/etc. into the fold.
As Ozzy states above, LE can get into any site, so instant access hardly increases the risk of LE presence. Moreover, most hobbyists don't seem to understand that writing a review of a commercial sex experience is not akin to prostitution and is not illegal (in the same way describing how to make a bomb is not illegal). I can give you the more detailed Constitutional analysis on this point if you would like. Separately, if your concern is that you think LE needs to read reviews in order to locate providers, think again.
Lastly, JAG does not require detailed address info. Telephone info and general location (e.g., "upper east side"), which is info the provider has probably already made public, is sufficient.
