And how would people buying from legit vendors benefit LE and their fake vendor account?... are you saying LE is watching everyone's mailbox that tried to order from them? Even if they did watch and we did order from other vendors, same CD rules apply... anyone can order anything to anyone's address.
This is really not that hard to understand. If I am driving my car around a "drug neighborhood" then I might get pulled over, searched and ticketed. in these same neighborhoods cops routinely run stings and reverse stings.
Why are you claiming that the cops wouldn't do this?
There's a big difference between the IRL drug market and SR, and this one difference is key to the safety of SR buyers. IRL, one of the main methods used by LE for rolling up drug networks is to bust low level users, get them to give up their low level dealer, and then move up the chain as far as possible. Under the right circumstances, one low level user bust could result in taking down a major drug supplier, and that is the motivation to spend the resources to bust occasional users. In the SR case, this does not apply. Busting a small time SR buyer doesn't lead to anything; the buyer knows his/her SR source only by the SR name and LE already knows the SR names of all of the SR vendors. Spending any significant amount of resources to bust an individual buyer won't lead to anything. No one at FBI headquarters will even get an attaboy by fucking around with small scale SR buyers.
Obviously, taking DPR and the entire SR structure down was a LE priority (senators are bitching!), and an easy bust of a large scale vendor and a few of their customers serves to instill some fear into all of us. I'm sure LE is happy about that, but I don't see then spending any time or effort on the average buyer. They'll maybe spend their energy on SM, BMR, and whatever new SR appears, although I predict that the next focus for the government will be wiping out Bitcoin. Don't kid yourself that they can't and won't do that.
Also - no one is going to be doing ballpoint pen ink lot analysis to bust anyone.
A little paranoia and a large helping of good safe practice is well worth it, but let's all keep some perspective.
