Vendors, if there was ever a time this is it, make your own onion and do your thing. Thinking about the bigger picture justifies this idea to the max.
it would be safer for both parties and of course make it harder for le. lets face it, common sense dictates that one of the easiest way for a market to get attention is from gaining a huge amount of traffic. its already been done by some vendors, who were being smart and professional in case the markets fucked up.
if you dont agree, send me your bitcoins and ill send you some chronic h2o that might make u change your mind :)
why would a vendor even need a .onion? just use PGP and email. The point is a middle escrow and that is what we will lose.
