I think you could share the name or username of the guys, with all the agencies and also with indies who have come together.
In the past there was another MERB BBFS thread in which John Eleganza, some time in 2008 or 2009 I think, publicly outed a senior MERB member for requesting BBFS from his ladies. According to John, the method or "technique" used was that he would fake putting on the condom all the way, and then pull an "ole!!!!!!" right before insertion. Just like the matador pulling cape away from the bull at the very last instant. John made it fairly clear that one of his ladies was totally traumatized by this action of BBFS (and I think she quit right then and there), and John was livid when he put up that post. I should note that I had never previously seen John make any type of accusation like that publicly, and he rarely posted at all outside of his own advertising thread or the review threads. Occasionally he did respond to bad reviews.
Later on, the senior MERB member John outed admitted to John's allegations on MERB (which kind of surprised me as I kind of knew the guy from parties and he is not someone I would have expected such behavior from). He sort of disappeared from MERB after that, at least under that handle. Identifying him in this post therefore serves no purpose, and this is all ancient history anyway but clearly this has gone on for a long time and in the past was handled in the fashion that is being suggested by Sene. I think that despite the admission of John's allegations that thread was later deleted by the Mods, perhaps because the Mods feared it was or would be abused to make false accusations. So I do not know what the actual policy of MERB is on the naming of BBFS aficionados by handle.
Even more ancient history is the legendary outing of another somewhat less well known and less well liked MERB member for BBFS. His handle was banned permanently by the Mods, apparently because there were direct complaints made to the Mods about him practicing BBFS by providers. This would be the infamous Robertpal, someone already mentioned previously in this thread. Robertpal had also been outed for shitting, apparently deliberately, while being serviced by a girl from Devilish. Right in the bed. Chris of Devilish absolutely excoriated Robertpal in a long thread, while announcing his banning from that agency very publicly. The Devilish ban preceded the MERB ban, as I recall. I met this Robertpal character around a year earlier at one of the MERB parties in 2005. He was a spoiled young rich kid hobbying on Daddy's money and seemingly just very immature at that time as he was like in his early 20s, if even that old. College aged. What I recall most about him is him spilling a drink on a girl at a MERB party at the HDLM. I witnessed it and it just looked like he was clumsy holding the drink, but the Devilish lady was furious to have had a drink spilled on her.

One other thing is that if the allegations about members is true and I do not know if it is, any agency has the ability to share the information with the Mods and ask that member privileges be revoked. I assume that this is exactly why Robertpal was so very publicly outed and banned and stripped of MERB posting privileges by the Mods. Robertpal later tried the Tony-like tactic of creating new handles and returning, but he seemed substantially less adept at doing so than Tony, as the Mods would quickly catch him and ban him again. But again, I do not know if the current Mods have that same policy or not as to what Sene is suggesting.
