Blizzard has something they call the "penalty volcano" to explain their ban policies.
|The Blizzard Penalty Volcano|
To all the newbros out there who just started playing EVE, CCP is not Blizzard. When someone at CCP thinks about a volcano, they worry about whether the volcano will delay flights out of the airports.

For CCP, hacking, botting, and RMT is serious business. Back in the beginning of EVE, the game was pretty vulnerable to hacks, as Greg Hoglund, the founder of HBGary and author of a bunch of security books, describes in the video below is from when he was promoting his book, Exploiting Online Games: Cheating Massively Distributed Systems, back in 2007.
To combat the problem, not only did CCP implement things like PLEX and improve the security of the EVE client, but they cracked down hard on those engaged in client modification. If CCP detects any type of client modification, like python injection, CCP will issue a permanent ban for all of the player's accounts.
Let me emphasize that last point. ALL. OF. A. PLAYER'S. ACCOUNTS. Unlike Blizzard, CCP believes in banning the player, not the account. If a player doesn't receive a ban on all accounts, that means that CCP was unable to find all of the player's accounts. CCP also has implemented a digital fingerprinting system, so when a player is banned and tries to create a new account, oftentimes that account is immediately banned also. The professional RMTers have ways around this and are willing to pay the additional costs involved, but CCP makes the process as difficult as they can.
So when I read the tears of someone who is banned crying about CCP banning all of his accounts even though he only did bad things on 1 or 2 accounts, I shake my head. Folks, I know most of you are EULA-abiding players. But if you do think about doing something stupid like bot or purchase ISK from shady RMT sides, ask yourself: do you really want to risk getting ALL of your accounts banned?
