Whether it be selling a different chem than was what listed (Example:Methylone sent when MDMA was ordered), an exit scam, shorting people, , blackmailing customers with private info, sending poison, working with LE, etc. Name the vendor who did it as well.
Unrelated but I have always wondered if someday some psychopath will get big on a market then start cutting his product with poison or some fucked up shit like that.
Why would a vendor put poison in his product? The whole point is to make money. Not many ppl coming to buy your drugs when all your customers are dead, LOL.
