Well, pirates don't translate themselves; they just re-translate what automated translators produce, and we all know how computers translate. That's why we see what we see, and I don't even know why pirates crack games and translate them so poorly... But if they do it, it means there's demand, so it all depends on us, dear consumers. If we don't buy pirated copies, they'll stop releasing them, but as long as there's demand, we'll often see bad translations along with buggy games from some random company. :(
