Well i have been playing for awhile and 3 months ago i'm starting to see problems with ranks manipulations... Most of the time its hard to spot and rank manipulator because i mainly follow these rules:
1) Do not use the !stuck or any other command to get away from zombies.
2) No MIC Spamming.
3) Do not block other players.
4) Do not break barricades after they are set up.
5) No glitching.
6) No whining.
7) Respect admins and other players.
8) No gay porn sprays.
9) If there is a problem, post in the forums.
10) Have Fun!
Breaking these rules in any way will result in being punished by admins. Punishemt is in the fourm of slapping, kicking and even banning for times ranging from a few mins to days and forever.
there are a couple of regulars i knwo who were convicted in this rank manipulation: from what i know it means a player spawns after the zombie spawn time, in order to become a zombie and tag all humans to benefit his or her rank. to be honest i have done that not for rank manipulation, but because some zombies don't put up a challenge and makes the game boring. a clan has even admitted to me that he has done it for the same reason i have.
however, i didn't know u can improve ur rank as a zombie. i found that out 3 months ago when a regular was banned because of it.
in conclusion i see the simplest solution to fix this problem and that is to make those zombie tags not count at all. for example:
-if a human kills a zombie (3 points) those points will count for his or her rank.
-if a zombie kills a human, that zombie will get a point BUT it will not count for his of her rank. its should be the same as getting 1,000 points in that Atix trick using a poison zombie. though it will show that that player got 1,000 points in the Tab-scoreboard, but will not count for his or her rank.
i feel that if we cannot change this, we may lose some good regulars and/or maybe even some admins
