Yeah, it is probably more of a headache, than it is worth.
Hypothetically, if someone were to purchase it for its "Private Message" value of AP content, the first thing that would need to happen, would be to remove the Trolls. I am confident, There are many AP's that would participate here if it was no longer a "sewer". There are many people who don't participate at WOV due to their strict guidelines. I myself have never had an account there. I do read occasionally.
Here is the thing... with AP information that is on an open forum or even a radio show like Gambling with an Edge, there are small little pieces of information that an AP can take from reading a thread or listening to an episode. So since a lot of information has to be sourced, to gain very little, or any at all, a person must absorb a significant amount of material. The last thing someone wants to do is read Trollish nonsense, to get to the small titbit they are looking for.
Here is an example of something that I have seen in the past of the type of information that can be scraped from users PM's. It was probably close to 2 years ago, a user that has been described as a "Multi-Carder" was communicating with another user that was going to use the cards to "Pick up the free play." I imagine the cards were sent via snail mail. Let's say the amount on the cards was shared in the PM. If the forum owner is an AP, and he sees the amount of Freeplay is, let's say mid Four figures monthly per player. Without even knowing what method was used to "build" the coin-in on the cards, he would know based on what he may be seeing in other areas, that this particular casino, for whatever reason it may be, is currently giving better "offers", than he is aware of elsewhere.
