Look at torrents, do people make money on them? No. Usenet, do people make money off that? No. Magnet links, do people make money off them? Nope.
Yes, big, fatass money.
Yes, PILES of it.
Same as torrents.

Take a look at this image:



ISOHunt also have 5 ads per one download page.
For one search you need 3 steps to get to desired link.
That makes 15 ad impresions.
Multiply that with 500K-1M daily users.
You can look at possibly 15M impressions a day.
Do you have ANY idea how much is that traffic worth?


Usenet. Do you know how much usenet providers pay affiliates for referring people?
Alot.

So, don't talk nonsense, really.
