I agree with m0rpheu5 - buyers expect to receive what they ordered. When someone orders LSD and then hears that a large percentage (or any percentage at all) is some unknown chemical, they have the right to request a refund. Why should buyers have to pay for the fact that the vendor was scammed by his source? It's the responsibility of the vendor to make sure that what he is sending out is what he says it is. The buyers requesting refunds aren't "scammers" - they are buyers who don't want to risk taking "LSD" that could actually turn out to be one of the DOB blotters. If it were me, as soon as I heard that even a single tab was laid with an unknown chemical, I'd have thrown out the tabs and requested a refund too. It's not worth the risk. This is why vendors should test this kind of thing prior to listing their product. At the same time, I don't believe that fuckingACE intended to trick anyone. It's an unfortunate situation for all parties involved.
