I remember wishing Galaxies had instituted bounties for people who broke the terms-of-service. I mean, bounty hunters were a major subset of player characters, after all! So far I'm liking the way it's handled in ESO. Players are pretty much solo-ing simultaneously. The presence of more than one player in a location only really matters for group events and dungeons, and those are marked so one can avoid them if one is dinking around on their own. The bosses tend to be more than one person can handle (sometimes more than half a dozen people can handle, depending). There are three ways PVP happens. Get the DLC that lets you go to the Imperial City, which is in turmoil at this part of the timeline, so it's a PVP zone. There are also PVP arenas here and there where one can go to test themselves against other players. Lastly, when one is out in the world, if you're in front of another player's character, the character's name and level and other relevant details pop up, including the key/button you should hold to interact. I've never bothered, but one of the interactions is to request to duel. If you don't respond or walk away, the request will go away again after a bit. No way to force PVP.
And, griefers aside, it is really hard to stay in someone's face and try to force them to take the first swing. You can fast travel, log out, go make a sandwich and leave the other guy standing there staring at your idle 'toon... Anti-griefing is maybe a bit of a hobby, one that I am pleased I haven't had any chances to practice so far in ESO.
