to craigslist 

(verb): to put up a missing persons report for someone on, as the name suggests, Craigslist

have you ever heard of anyone trying to craigslist someone else? I mean the missed connections section doesn't count, since that person you are 'looking for' probably wouldn't see your ad anyways, doesn't want to talk to you

to Craigslist 

(verb): to put up a missing persons/missing pet/missing antique car (for cars it is only in cases where people love their cars more than their actual significant others) report on Craigslist, but specifically in the lost and found section- a section designed for inanimate objects.

IMHO, if you do want to Craigslist a missing person, a missing pet or a missing vehicle- which, although unusual, is absolutely your right- please don't make a fool of yourself, and be kind enough to put your ad not in the lost and found section, designed specifically for inanimate objects, but rather in the missed (emotional) connections section.
