A copy and paste from an article about EQ names:
SNERT: Snot Nosed Egotistical Rotten Toon. Insult usually applied to players who play in a manner that is offensive to other player ( Not to be confused with a player who is role playing with in the character’s race, class, or diety) or a player who has a character name that does not comply with the Naming Policy.
Pickle: A.k.a Pickle Jar Label. A player with a name that is not with in the fantasy roleplaying genre. Example: Manapumper, (it is a name that says what a character does) Sournote Playsouttatune (a bard), Rezzyou (a cleric)
The nameing filter can't catch all the inappropriate or offensive names out there. According to the fine print in your EQ Manual, names are supposed to be with in the fantasy game genre. It seems that the dozen or so real GMs out there just can not be online all the time, scanning all the servers for SNERTS and Pickles.
Along with what others have posted, Names ( first names and surnames) should not contain a title like: the, mage, lord, sir, mister, miss, prince, lady, princess, sister, brother, godess, of , and god. Many of these are titles or rewards earned in the game and the players who have really won or earned these title are annoyed by someone just wanting a "power-trip" name. Also naming policy mentions that names that are off by just a couple of letters, or intentionaly spelled phonetically to imply an offensive term or title are also not acceptable.
The bottom line seems to be that if a name offends you, please /report it. The petiton system is so whacked these days its hard to use.
