Poundlanduk2uk has sent out letters claiming they're from Dream Market, titled the "Dream Market 2018 Idiot Tax".
This is his pathetic attempt of extracting funds from people.
Ignore it, and don't send any funds.
(There's a picture of it I posted on r/darknet if you want to see it.)
Yeah i got one of these. This really does make life harder as at some point you have to give an address to someone to get a delivery, regardless of how careful you are there has to be an element of trust. Now this has been well and truly eroded for me as after a few years of trouble free trading for small personal amounts i got taken for a big chunk of change, which i swallowed (painfully) and put it down to experience, now i receive a letter trying to blackmail me. Yeah it is a shitty low thing to do for sure, will just have to see how this pans out. I'm lucky in that him telling the authorities will be an inconvenience but for some people this guy could be breaking up relationships, getting people fired, getting people arrested even prison time if they are unlucky but above all this, this kind of pressure can make people do drastic things, i know i wouldn't want someones suicide on my conscience because i tried to squeeze a bit too hard. I'm sure he is aware of the threads that have been started on his blackmail spree, hopefully he will get a few takers and call it a day, but ultimately he is threatening to snitch, its rule number one in any code, never snitch.
