They're pretty much disallowed because if the user has not caused trouble yet asks the mod to ban them, it could create problems for the staff because bans should ONLY be used if said user has caused trouble by insulting other users and staff members alike, then that counts as a ban. Bans used just because they asked to are simply frowned upon and therefore, its best that the user should voluntarily leave without asking the mod to ban them.
