I dont use craigslist... somthing irks me about a site that allows the posting of prostitution adds but not firearms items.

In a way i boycott them.

In their terms of use

"Partial list of items the sale of which is not permitted on craigslist:
Weapons and related items, including firearms, disguised, undetectable or switchblade knives, martial arts weapons, sniper scopes, silencers, ammunition, large capacity magazines, BB guns, tear gas or stun guns. "
