I don't think it's Pete's fault at all for what he posted. It seems like he didn't even know this guy was a part of these forums. I didn't anyhow, and from reading what Pete posted that's the impression I got. Posting the name/email address of the other guy involved is pointless. Pete wasn't asking us to solve this problem between them, but to simply give the name of someone who may have questionable business ethics, if nothing else. The name or email address of the other guy would have been useless information. I took what Pete posted as simply a warning, which I think it was meant to be. He didn't say anyone did anything wrong, just said something wasn't right with the situation.
