Well there is some what of a way to find the person. Only if you know his coordinates which would be nice when your reading your message of who defeated you it had that information.
First off, this idea is stupid. If you want to retaliate take the time to look for him, or ask your crew/family. Heck, even ask in all chat. Generally an offensive player is well-known and you can get their estate coords easy enough.
Second off, as William said, the people who play the right way are enjoying some PVP action. The main issue with not enough PVP is attack orders. We can't do enough PVP because we can't send out.
Third off, if I take the time to search and search and bust my butt finding targets, why should they have the easy way out of being able to retal without any effort? That would turn people off from attacking even more, not encourage it.
Fourth off, this is just a typical suggestion from another lazy noob who isn't willing to put forth the effort to play the game and expects the game to cater to his own lackadaisical playing style.
