Operators of illegal sites often couldn't care less if you pay for their so-called services. Their primary goal is to get you to click the ads or to download iffy software from their servers. That's why they use huge fonts and flashing graphics to emphasize the word "free."
Free, of course, is a trigger word that sends many consumers into a mouth-frothing frenzy. Click a few links for a free movie? Why not? Oh, I have to click a bizarre graphic for Indonesian cheesecake first? No problem!
That's exactly the mentality that illicit site owners hope you'll follow. Legit sites, on the other hand, lure users with a few streams but hold the good stuff closer to their vests, hoping you'll ante up for a subscription or at least a one-time fee for the right to play their content.
Free lunch? When it comes to streaming movies from obscure Web sites, don't bet on it.
