This answer is not good enough and raise more questions.
First question is why rules of conduct do not mention numer of free attempts before considering that rules are violated.
As much as i read first rule of conducts i cant find any mention of free attempts bonus.

1.While playing Lineage II, you must respect the rights of others and their rights to play and enjoy the game. To this end, you may not defraud, harass, threaten, or cause distress and/or unwanted attention to other players.

Next question - as to make player red and to make him pk count 5+ in order to get him to drop items is very hard to do it solo need to be organized group of players or their boxes to do it so is hard to determine who did how many attempts.
To do player red with pk count of 5+ must be at least 5 attempts. As I newer heard that ppl got banned for it I must guess that number of free attempts must be at least five.
Why we have this first rule of conduct if it have five free attempts then as is same as we would not have this rule.
Do we know any country in real life selling weapons in weapon store with free kill bonus?
And what to say for victims that do not use any macro and are not afk when they get friendly (no drop) killed together with all party repeatedly aka ColdShadow mode?
How many free attempts before considering L2 store paid items, services and benefits as not delivered (cake, xp scrolls , runes, potions ect) because expired in process?
Question is also why rule of conduct were not changed when NCsoft introduced L2 store and changed from subscription model with 20$ monthly into pay to win free to play model for several hundreds (and thousands) $$$ monthly?
Off topic maybe - did anyone reported a bug that set next target settings on monster do not work at all as it values players as monsters ?
Who care of player color or multicolor (white, pink, red) as setting is set on monsters and not on players.
Setting is bugged for all classes and specially on classes witch cant deal damage without using skills like feohs and all classes using aoe.
So if official answer that game mechanic work right when someone flag you then remain to believe that settings on monsters only - is full bugged.
