i always add " make sure you specifically identify the item you want in your email or i will not respond" in my craigslist ad
anything that only says "item" is just a bot or scammer trying to get your personal info
last one i got they offered me an extra $300 for the item if i would ship so i told them to use the extra $300 for a plane ticket to come pick it up at my listing price...they didnt respond
