Opinion as one of Eastern European blood who is very much aware of the underground business customs/practices of defunct Soviet folks in shady businesses and "unclean hands" rules of engagement (noteworthy, my parents' are cut from the same corrupt cloth, but they left their cut back in pursuit of liberty to work hard but clean to claim peaceful sleep), can weigh in on MDS for what it's worth. There's a Slavic saying that remains true to its words yet: An agreement is worth more than money.
Virtually any direct post-Soviet country and alike across the Far East in terms of business fair dealing and principles are along the likes of China; as long as what MDS is exporting is legal in Ukraine or wherever he is and follows all laws (which may now include paying a PR liability tax to the local city mayor on all profits and is issued a warning that if his enterprise gets too hot, he'll have to mysteriously die by natural causes (he'll be ordered to take a taste off his own medicine; that or become part of the highest suicide statistic globally in Russia/Ukraine/East by Russian Roulette or Poisoning from unknown causses, but Slavic mentality is more opportunistic than scamming and they deliver as long as you pay.
As far as him being Doxed, the worst that could happen is a visit by some corrupt Corporals forcing him into indentured servitude by making him their chattel slave mule, and he'll have to surrender a large portion of his earnings and ongoing profits to corrupt officials.
Thus, the BBC article now backfired big time since his identity Doxxing not only assisted corrupt authorities leading them to his door, but gave rise to a new opportunity for even broader "harms" if you will by state-sponsored oversight of the continuance of SN sales from Ukraine and if not, Russia for certain, possibly now through multiple channels opening up en masse. And trust me, Russia will find a way around logistics. They'll use Turkey or Serbia as middlemen shipping freight forwarders to get around the shipping sanctions and direct to USA with stealth you'd be impressed with all within 12 days (trust me, I know a friend who orders medication from Russia even Profonol, and always lands without ever a hiccup.
BBC just sparked more demand and now reliable suppliers overseas which are a major blowback to the article's sponsors and new suppliers that'll be entering the market with possibly even other lethal fairy dust toxins like cigarettes in Russia laced with fent and RC Opioids ... yeah, they're still around and the government's turning a blind eye if run by a major connected group with contacts at high levels, but now possibly fent laced cig packs that could be the last nail in a lot of coffins. From Turkey or Germany, in cigars too as a truly last smoke especially with tensions rising against the West, Russia's interests are not in your best.
Most all of the Russian-run DN platforms have never exit scammed voluntarily, except by rare LE takedowns when operators began moving servers and their domiciles away from their mainstay in MoFoLand or in no foul force majeure fallout. Recall the longest operating DNM since memory is still running strong by a Russian group in bed with the FSB (by now) and they're state-sponsored blessings of server rack space and DDoS immunity are still operating smoothly while all other non-Eastern players always end up blowing scams and landing their scum asses on the slimeball of shame legacy AWOL mugshot book.**
**I suspect because it's origianal founders were either caught at he behest of the FSB and enjoined to continue operating in some all-in-bed deal where they'll be state-sponsored with unlimited server and IT rack space distributed worldwide by Soviet friendly or neutral countries sufficient enhough to handle DDoS attacks and unique user/vendor dedicated private onion links ... its no wonder they're mysteriously always online. I'm not naming the site to not promote Red Army revenues. But it's a testament to the way things work there and culture tuned to the traditionl Slavic saying: An agreement is worth more than money.
