Griefing
From YPPedia
Griefing refers to harassment of another player. In Puzzle Pirates, this includes sending abusive or threatening messages, stalking, and other forms of social abuse, but especially refers to in-game actions intended to cause pain and frustration, such as frequently-repeated PvP attacks on the same ship, nuisance blockades, etc.
Griefing is a violation of the terms of service.
