Lotsa legitimate points here!
I understand where you are coming from Zazen, putting some value in the top 100 and trying to legitimately get in there or get as high up as you can. I think it is a measure of skill, upping, getting kills and landing them is sort of the whole loop of things.
However, "anything goes" is sort of the accepted deal now and there is a certain amount of validity to that as well. If that will that devalue the game, only time will tell. For the average player, I think probably not.
Zazen, I think you can find some comfort in that the vast majority of the player base doesn't alter their score artificially by vulching ghosts. Now I know that sucks if you are ranked #101, but still the overall rankings aren't going to be skewed by very much at all, I don't believe, because not many people do this activity.
