PVP token script [Need Altered]

[Etymology]

Hey, I have a server were people keep opening two WoW's and farming an account for the PvP tokens..

I saw somewere that this can be edited, to reduce the farming..

Basically, if a person is killed more than twice in a row by the same person it does not supply a reward..

Anyone help me out?

The Item ID is 29434

You just need to store for each player the last GUID he killed. Search for std maps.
