Sadly WW?...that can only be answered by the one with the knowledge of the facts. That would be you.
I would suggest you...
1) Step back and determine your motivations. Are you doing this for noble (good of the community) reasons, or vindictive (personal vendetta) reasons?
2) What is the severity of the known infraction? In other words, an infraction that involves a Diamond talking some idiot out of a few extra dollars is not the same as an infraction of blackmailing some Tuxedo. Of course as we know, in real life, there are all kinds of shades of gray inbetween.
3) Based on the severity of the infraction, is there a way to provide this information in a less obtrusive manner that has less chance of unintended consequences?
4) Finally, in the interest of self preservation, you had better make sure whatever you do does not have a way of impacting you negatively...at least not in a manner that has any real meaning.
But in the end...it is up to you. You weigh all the facts you know, you make a self reflective check of you own shortcomings, and you take a step into the unknown (i.e the future)...and you live with the consequences. There ain't much way around that.
Somehow I think you know most of this. But we all look for that magic formula that tells us the right answer. Sadly, most of the time, there ain't one.

Without too much collateral dammage. This isn't just about one provider but a series of them and the acts range from blackmail, extortion, theft, outing and some that seem worse.
My proof in some of this I was directly involved, in others the proof is out there on the interwebs for anyone to see. One of the provider personas that concerns me was removed after this thread was started. While this might be shocking to me, please note very heavy use of sarcasm, or Wakingup few of the Diamonds or Tuxes would be surprised.
In most all of the cases and I want to be really clear about this, it isn't a one time misunderstanding or a moment of confusion about a "loan" to a provider, this is seriously bad shit. Some lost a job, someone had their real name posted on the internet linking them to this world. Someone was threatened on this board in PM or email. In other cases we are talking about a pattern of several handles for one provider that are linked to some pretty wrong behavior, cash and dash, blackmail and out right theft.
Of course in the things that affected me directly my motivations are suspect, how could they not be. In other cases sure I might not like the person involved but how much of that is personal animus and how much is based on their behavior, no easy answer to that and it's one of the things I'm looking for help on. If the pattern of behavior is bad enough, does it really matter or isn't the information the most important thing.
As for my personal rep, it's just not that big a deal to me anymore, I've been called everything from a Murdering Rat Bastard to a baby killing rapist, been around long enough for most to know my actual nature. Sure I make mistakes get it wrong now and then, but can admit it when I do, apologize and move on. The notion that I am famous for paying a lot of women for their time over a large number of years is amusing but not a real part of my sense of self.
