While I personally never received anything from any deep web affiliated salesfolk, I did live with a roommate who would constantly receive the strangest brochures.
At first we'd receive brochures for like, cruise lines and the like, I wrote it off as junk mail but they came so frequently, and they started getting stranger. christian mingle brochures, petting zoo brochures, brochures for any and all services one can think of. I kind of felt like someone was gaslighting me but I never said anything and the brochures would disappear as quickly as they came so I didn't have time to stress it, until one day I walked in and my roomate was delicately cutting into a brochure and pulling out a small baggie of powder, ♥♥♥♥♥♥♥♥♥♥♥♥ had hooked up with the most low key dealer I'd ever seen!
