Eve Online Pirating / scamming, and everything else god has forbidden:

This generally means letting other people make money, and you take it away from them the "easy" way, this includes scamming, pirating, gatecamping, etc.

Scamming:
One of my personal favorites. Im not gonna go into details about how I do it, but lets say I didnt exactly mine for that raven of mine. This basicly means using the stupidity of others, I will tell you people some old scams though so you might think of your own way:
Selling shuttles for 10 million a piece, selling minerals for redicilous prices, putting a condor named scorpion in the trade window (they used to look a like), etc. Scamming is commonly done with alts, but this no longer works becouse people know alts are being used and won't buy from them. Scammers can however expect to become outcasts and can expect to no longer be appriciated if this gets known to others. It can definately be the most profitable thing to do, but it will get you on more blacklists then pirating itself will.
EVE Online Scammers Guide

Ore theft:
Now I have to admit prior to making this guide I wanted to know what it was like, so I trained an alt to fly a small basic indy, within 2 days I was on the KOS (kill on sight) lists of at least 3 alliences. This is the most hated profession in the game, it makes about twice the profit mining normally does. You just basicly get an indy, sit in 0.5 and grab the unsecured cans of poor miners (they can attack without police responce as of yet). Sometimes they will attack you, with a nice explosion as a reward. Can flipping is often done by people in fast ships. You basically steal the ore from a miners can and put it in your own can then run away. That way when the miner goes to take it back they are effectively stealing it from you and will therefore be flagged as a criminal, allowing you to pop them legally!

Pirating:
Now the real forms of pirating would of course be killing miners/npc hunters and camping gates, most people see pirates attacking alliences, but I consider these people to be space vikings not real pirates (m0o for instance). This profession can be among the most profitable around, if you're lucky (and any good) you can have people ejecting from their battleships to save their pods, and you can collect an easy 30 million from most smart pilots that desire to live. Unlike what most people think pirating is commenly done in 0.1 - 0.4, not 0.0, 0.0 is usually filled with groups of people, this usually ends up in a fleet battle, and not a fast miner holdup. To start the way of pirating described here you used to only need a blackbird, but since the nerf you need a little more, you also need to make sure friends are not to close, and you need to put preasure on people. however blowing them up is not much profit so negatiation is a must.

Corp theft:
Among these are the most famous, hated and richest people in eve. It means betraying friends you've been with for months, and often means being hunted to the end of the world. Some examples of these are agent shield (who corptheft after his corp let a corpthief join, dual corptheft). and Fallzone (who stole form the richest corperation at the time).
This is a profession most hated and it will not get you friends, even among pirates. But it will get you immense wealth, after wich you can sell ur account...
