What is grief play?
http://support.eveonline.com/Pages/KB/Article.aspx?id=336A grief player, or "griefer," is a player who devotes much of his time to making othersGÇÖ lives miserable, in a large part deriving his enjoyment of the game from these activities while he does not profit from it in any way. Grief tactics are the mechanics a griefer will utilize to antagonize other 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.
An example of grief play would be the so called "Can baiting" in starter systems. An experienced player drops a cargo container with some items and waits for a new player to take from it. The new player is flagged and promptly attacked and killed by the owner of the container. Doing the same in the systems the Blood Stained Stars epic arc takes you through is also considered grief play and will not be tolerated.
