Griefing refers to the act of an offending player (i.e. the griever/griefer—one who causes grief) purposely ruining other players' gaming experiences by exploiting aspects of the game in unintended ways or disrupting the community. This also includes spamming, which is reportable under Rule 14. Griefers derive enjoyment at the expense of other players.
The most obvious form of griefing is constant stalking and harassment of another player.
Trolling refers to using subtle insults to elicit responses from others or goading an emotional response out from someone. Although griefers and trolls behave in a similar manner, such as annoying and attention-seeking, trolling occurs largely on chat or forums and individually.
- Harassing, stalking, insulting players, or making real-life threats—Rule 1, 14, and 15
- Scamming—Rule 2

- Sniping   
- Door closing
