Shit doesn't add up, why would a market spend so much time and effort on coding and fixing bugs only to be in existence for 7 months and scam for a measly amount (only 3 large vendors ever used Oasis). Unless they were cops after all.
They took every damn suggestion given to them and coded the market to fix all of that, and cops in the past have shown how good they are with computers by hacking/de-anon TOR and busting SR etc.
I think there is a change in tone of Oasis's reddit account over the last few days before it went down, I could sense some sarcasm in their replies.
So LE allowed 1000's upon 1000's of hits of LSD to be distributed through out the world for 7 months.
