I have played EVE online and I thought the security system is pretty a good idea. For newbies, they are protected when they are near to one of the first three cities. When they walk far and far away their security level is going down and more PvP is going up. If they allow open-world PvP, they should add an option for PvP-haters to ignore all PK requests. In my opinion, PvP should be testing in an arena first.
