I'm not sure if using the term "witch hunt" is correct, since so far I only see this topic as a device to make people aware of organized afk leeching. I doubt a dev is going to reply to it since there is no solution that won't harm all other players. I don't see anything wrong with notifying people of this exploiting and if they actually respect themselves as proper and legit players to not get involved with others who are organizing afk leeching.

I'm not going to say I know why everyone plays MMO's, but my own reason is a sense of achievement which is unobtainable playing console games offline. I enjoy the feeling of achievement that is rewarded to me by the legit hours of game time and effort I put in to developing my character and learning how to play it the best way possible.

I am worried for not only myself, but other legit players who are starting to see afk leeching parties too often in this game. It is disheartening to see my effort cheapened.
Even if there is no way to stop afk parties, legit players have every right to avoid players who are involved with organizing afk parties and it not being coined as a "witch hunt", rather it being the only way to happily continue playing the game.
