I said i can think of at least 3-4 ways to abuse or miss use it if i wanted, 1st was bribe 2nd is plain ignoring 3rd Well the one that will be most popular new in experienced players using this few days ago a new player came in the game some one told him got to /su bam 10 min later 10 players on the server 9 suspected... 4th and final way is Pick up if you dislike the player who called he cant know who picked up and since you picked up he cant re dial he will be neutralized totally. These are 4 i could think of in this moment, if some player who knows game mechanics more would use this i'm sure he could find few more ways for sure.
