Gray Spraypaint is a slang term for when an administrator bans a user. Banned users, having power level -1, have gray user names, which is where the term comes from.
There used to be a weapon in shop.php called Gray Spraypaint. It had an attack of +2500, defense of +100, intelligence of +500, magic defense of +100, dexterity of +100, luck of +100, and speed of +100. This weapon also doubled the user's hitpoints and magic points.
