On the Darknet, Reputation Is Everything
I think it's a really positive thing that people are able to leave reviews for drug purchases. In the absence of FDA regulation, a public reputation system incentivizes dealers to avoid harming their customers with dangerously-adulterated products.In the midst of an opioid crisis, with people overdosing on heroin cut with fentanyl, having this accountability can save lives. There's a subreddit (whose name I won't mention) that facilitates meetups between opioid sellers and users, encouraging buyers to leave feedback once the meetup is complete. I'm glad it exists.
