Well here you have your question, and your answer. Both from yourself.
I also already proposed that bumper is deactivated by default, and activate it only when security is yellow and you are suspect/use a specific module that makes you suspect (but would help you bump, eg a 500mn with increased mass and thrust).
I think it actually depends if CONCORD is already present in the system. If they are not they will spawn right away next to where the criminal offence happens. If they however are in the system they first despawn wherever they are and after 6s they spawn next to the criminal.
If you get popped during that 6s CONCORD will not spawn and you have effectively despawned the squad, which means that you don’t get the extra 6s on the next gank.
Please correct me if that is wrong. This is based on simple observation.
So I sit on the Jita undock in an unmoving bowhead. Everyone who bumps me as they undock becomes a suspect. Not a good idea and too easily exploited.
But not all flying is done this way, nor is good bumping. I turn on my prop mod. Then using my arrow keys (short cuts anyone can set in the short cuts menu), I can pilot my ship.
I could fly into someone using this method and never once click approach. I can also use this method so I hit a ship in motion if I time things correctly instead of hoping approach works.
“Gank” is a portmanteau of “GANg” and “Kill” (alternative according to google is also “gang” and “shank”). Any situation where you are ganged up on is a gank. Which makes up a large number of Eve PVP.
A grief player, or “griefer,” is a player who devotes much of his time to making others’ lives miserable, in a large part deriving his enjoyment of the game from these activities. Grief tactics are the mechanics a griefer will utilize to antagonize other players.
This should not be confused with standard conflict that might arise between two players. At our discretion, players who are found to be consistently maliciously interfering with the game experience for others may receive a warning, temporary suspension or permanent banning of his account.
There is a link in the old forum post for a direct definition, but it doesn’t go anywhere.
Bumping could be interpreted as griefing by CCP… except that they generally don’t see it that way.
Common Misconceptions about Exploits
This passage contains common tactics and other player conduct that is often mistakenly reported as exploits but are in fact not.
Ship Bumping
Ram the ship of another player with your own in order to prevent them from warping.
OTOH, griefing is determined on a case-by-case basis at CCP’s discretion. A 6-hour bump session could be deemed griefing - or it might not. Depends on how the individual GM feels that day. /shrug
