Eh…. Piracy is a tough one. As one of the wee little people who is lacking a "non internet dependent income stream" I find myself internally debating it all the time. On one hand, the pirate sites (which shall remain nameless) do serve as a fantastic resource of free advertising. When something goes up on those sites I usually see an increase in sales and subscrips. The downside is that most "sharing pirates" tend to lack any sense of restraint or common sense, and post as much as they can, as fast as they can. At which point it stops being beneficial, and starts hurting business. Tons of stuff posted at once is bad. And it's even worse when it's the new stuff.
Regardless, any time I see a set go up on one of those sites the "greedy money-grubbing capitalist who likes to be able to pay rent and eat from time to time" cringes inside me. So I generally have to take a moment to step back, let the blood rage fade, and gain a bit of perspective. The first and foremost the reason they are "sharing" it, is because they like the work. So that's good. So keeping that in mind I send them a nice polite email explaining my side of the issue and some gentle requests. And on the rare occasion that doesn't work, then DMCA the fuck out of them! Burn their village and rape their livestock.
