*Ok what about persistent pirating ?
*Agree about hackers and cheaters
*Does that mean if I dont like somebody i can report it too ? Or its just when someone is cursing and offending You ?
Again what is the "persistent griefer" mean exacly ?
Report anything you want - it's there to get help if you feel you need it. FD would deal with problems on a case by case basis. If you don't like someone FD would probably advise you to put them on ignore / mute them. If they are harassing you then FD would take action.
I am not sure what you meant by "Persistent pirating" - Do you mean someone who is always a pirate (like I will be) or someone who keeps picking on you ? If it's the former then that's a valid role within ED so deal with it; if it's the latter then either go to a different star system or ignore them.
A "persistent griefer" is someone who causes issues with other players (outside of the game rules) and despite warnings by FD fail to stop. Griefing can mean many things of course but its usually someone who's objective is to ruin yours. As this is subjective it's down to FD to determine any repercussions hence the report button.
