It's entertaining for sure but lets look at things realistically. How many people are going to let you film them while they perform illegal activities and don't mind their faces being shown to the world? At best it may be a re-creation of moonshining.
At any rate it's better than watching every Tom, Dick and Harry destroy the earth to find gold. Worst of all is Bamazon, where they are using hydraulic mining in the middle of the Amazon. At least in Alaska there are mining officials who make sure plans are in place to cause the least destruction. But to go to another country were rules are lax and take advantage... I hate those people are from my neck of the woods.
Back on topic, those people on Moonshiners do have a lot of skill and are willing to work hard. But again I find the whole concept hard to believe. At least on Drugged and Drugs Inc they hide their face and alter their voice. It too could just be re-creating, but I find it easier to swallow, so to speak. I mean I personally find drugs a lot easier to swallow than alcohol. And I've had some bad drug after effects, but nothing like my worst hangover. Well, maybe I spoke too soon. After recalling some withdrawals I've had maybe a hangover isn't too bad. I've never used alcohol long enough to be dependent, but I've seen some people going through DT's who looked as miserable as one could be. I suppose the effects of getting dependent on anything and withdrawing is awful.
