Not sure how much this helps.. but I'm trying to respect privacy of these people by hashing.
Md5sums of p aypal e-mail addresses I've successfully traded with via bitcoinmarket.
obviously md5sum is not infallible.. thus don't assume a crazy address like email@example.com
is actually one of these people I'm speaking about. all were normal addresses. :-)
ps.. if anyone would like off this list pm me. http://md5-hash-online.waraxe.us/
<-- to generate md5sum of an e-mail address to verify from this list.
