as far as i see it he atackt you first by raming you without a rp notice thus breaking this server rule : 5.2 All attacks must be the result of some form of role play. "Engaging" is not sufficient. An attack is any hostile action that drains shields to less than 50%. Being hit with a CD is not considered an attack. If a player is attacked he has a right to defend himself regardless of who is attacking.
also here are some more rulles wich might help you : 5.3 Characters that are level 29 and below may only be attacked if at least one of the following conditions is met:
a) They do not have a civilian ID. Recruit IDs should be respected if the person is using it appropriately.
b) They attack you first by draining your shields to 50% or disrupt your cruise engines.
c) They are at the scene of a battle between yourself and someone else and refuse to leave when told to leave. (Civilians should leave the area when combat takes place or accept the risk of being attacked if remaining. Onlookers are fair targets.)
d) Civilians who possess a CODENAME weapon may be attacked within roleplay at any level according to the piracy requirements.
.
also if he dies and keeps to get death this rule still aplays : 5.8 A player who was killed in a PvP fight must not attack the enemy (player or players involved in the death) with any of the characters on his/her account(s) for 4 hours. Self-killing during a PvP fight is counted as a normal PvP death.
now i know there was/is a oficial rule about ramming but i cant find it anywhere.
in any player contact wich will result in pvp i make screenshots. also how he/me died and such. if someone ever would make a report i have evidence with chatlog on just to cover my back.
hope this is helpfull , and if someone knows the location of the ramming rule please post rule . Friendly greetings from
