The in-game stuff is the tip of the PVP iceberg as far as Eve goes. Whole alliances have been killed off using a handful of reddit sockpuppets impersonating their members, brought down by a player flipped at a social event, or simply imploded under the weight of internal drama stoked by rivals. Often all 3 at the same time.

It's a very interesting game, built on a really crappy space themed spreadsheet.
