NBSI
From Backstage Lore Wiki
Not Blue Shoot It (NBSI) is a engaging policy usually employed by corporations or alliances that operate throughout low-security or null-security space in New Eden. As its name suggests, a player who follows the NBSI policy will shoot any pilots whose standing is not set above 0 to make him appear blue on sight. Standings can be set on a corporation or alliance level to distinguish between allies and others.
NBSI ensures that any non-friendly pilots are killed before they could cause any damages to the alliance or corporation, thus creating a safer area to operate.
