While playing the game, there has been a specific user (No names but you all may know them) who has been spamming the Novice and World chat with very awkward, creepy, and pedophilic stuff. It isn't quite crossing the border into being able to report the user, but its obnoxious and most people are incredibly put off. While some of you are seeing griefing as inherently bad, immature, whatever, It is an incredibly useful tool to keep users off the game that are trying to cause problems, be obnoxious, and make the community a bad place.
Me and many others wouldn't waste our time PKing randos because we have better things to do and don't want to serve the jail time, but if by griefing we can force bad users off like this, then lots of people would *gladly* take the jail time. Because they feel like they are making the game and community better. Without a PK mechanic we would just have to keep enduring this persons stupidity in world chat until they got bored (And there is an endless amount of people to rile up, so who knows when that would be), So its better to just grief them and make the game a pain for them to play until they leave.
People have tried talking it out verbally, but that just encourages the troll even further. When talking amongst adults it is fine and respectable to be diplomatic when trying to deal with issues, but when dealing with trolls and verbal griefers, oftentimes the only way to get them to truly go away is to grief them back and make the game not fun.
If people here are so sensitive that they can't handle a minor setback from the occasional very rare stray PK griefer, they probably can't handle dealing with the trolls that would constantly flame world chat either, or maybe they would just isolate themselves further and turn off all chats (seeing that these people don't have friends to help them if they are getting physically grief'ed either) but at that point why are you even playing an MMO? Honestly.
Well said trolls just have to chill somewhere in a save zone, and even PKers cannot touch them. So this also isn't efficient. Even if they were in a PK Zone, you would still have to find them first etc.
It isn't so much about finding someone and hunting them down the moment they annoy you (Although there is bounty hunting for a reason), but more so identifying obnoxious people and adding them to a "Kill on sight" list. Yes they can sit in a safe zone for all of eternity, but that isn't particularly fun even for trolls. Their game will get significantly more limited if they build up a reputation where everyone wants to kill them the moment they leave a safe zone.
