1.kill gmg until normal zoners rep is very close to go red but still white, cause a triple or quadruple bribe wont show up with a higher rep
2.tripple or quadruple bribe zoners in the gran canaria bar, i never took a double bribe cause it takes longer to repeat all the steps instead of just log onto another char and then relog back to the char i want to tag until the tripple bribe shows up
3.repeat 1. and 2. until zoners guard rep is at max
4.drop missions for all the factions that have full green, in my case that where lwb, corsairs and kruger minerals. this will prevent your rep from the so called leap-frogging.
5.kill gmg so the normal zoner rep isnt blinking anymore
lets just say guard tags are never influenced by killing npc, except the npc related to said faction and the guard themselves.
which can be a good, and bad thing, really.
but for zoners, unfortunately, the only way to get guard is a mega bribe.
