It's never going to happen for these reasons:
(1) The Mods are unpaid volunteers, they are not compensated private investigators who collect information and who actually have the time to do what you are suggesting they do;
(2) As demonstrated by the sticky threads on this subject, they were largely ignored proving over time they were useless based on the many one off threads that showed the poster hadn't bothered reading warnings that had been posted for months or years;
(3) if you guys bothered to read those threads you will see that some of the B&S providers were MERB advertisers, so how do you realistically think the Mods would overcome the conflict of interest you would foist upon them? Answer: they won't, and can't, because they are unpaid volunteers who operate at the behest of those who own the board (much like Comey operated at the pleasure of Trump).
You guys need to be realistic. The best you are gonna do is expect members to update the existing sticky threads. Since it hasn't happened in 12 years and still hasn't happened, this thread kind of proves the uselessness of the endeavor.
Basically, it's a Buyer Beware situation. Do business with well known and well reviewed agencies and you probably have less risk. Use relatively unreviewed agencies and providers and you assume the risk. There are plenty of MERB members who willingly take on that risk as demonstrated by the many "one off" threads which really only established that they had not done any research and took a chance. One guy even posted that because an advertiser was on MERB, he thought they were necessarily above board, vetted and approved. Why he would have thought that is beyond me because to my knowledge MERB and its Mods ain't doing background checks before they accept advertising payments. Do you do background checks on your clients? Come on now.
