ermmm i did somethin very similliar to one tao
maybe it was even u
way i did that:
char botting must have casted guard and be on capture
u just attack him with some noob getting flashing name and when that tao get weapon skill like snow or w/e it will hit that noob and kill it... then u just rev him and that guard will keep killing noob so ull be getting pk points
do it few times to get suspicous target red and then just pk with high lvl char and test your luck if u get somethin
