Regarding server rule 3. - RP must be done in system or local chat?

[Stone21]

3. All attacks must be the result of some form of justifiable roleplay.

3.1 An attack is any hostile action that drains shields to less than 50%. Saying "Engaging" is not sufficient and aggressors are not allowed to destroy a ship before allowing sufficient time to respond. If a player is attacked he has the right to defend himself regardless of who is attacking. Trading nanobots, shieldbatteries or other ammo and equipment during a fight is also considered taking an active role in the engagement.
3.2 A player who was killed during a PvP fight in any form, must not enter the system where the fight took place or re-engage the attacker(s) for 2 hours from the time of their destruction, or until this/these ship(s) leave(s) the game.
3.3 Aggressors are not allowed to issue further demands during the same encounter after the trade vessel has complied, or destroy a trade vessel prior to issuing a demand, in system or local chat. "Halt" on its own is not a demand, however, a trade vessel can be destroyed if they refuse to stop after being asked to in the form of a proper demand.
3.4 Fleeing from combat and then docking at a station or planet while you are in 10k range of the ship you were fighting counts as PvP death. Freighters and transports in this case may return to the system for the sole purpose of trading.
3.5 Roleplay is required before attacking or destroying a player owned base. The roleplay regarding this must be properly documented on forums, with the link(s) posted in this thread and should match the roleplay and conduct of the characters involved based on the faction they belong to.

Recently someone who's on my ignore list for private chat started some shooting but there was no system or local chat by him.
I guess he addressed me on private chat.

Now after checking the rules I think there should be an addition that roleplay is required to be done in system or local chat.

These private chat stalkers are really annoying I have to say.

I agree with you. These private chat stalkers are a pain. I've been through what you just described but I figured out the player was on my ignore list because I can't forget who I add to ignore list. Great feature that is !
