Where are the abolitionists to banish Craigslist help wanted ads

Since the abolitionists feel eliminating advertising venues is the only way to prevent a tiny percentage of crime. Why are they not calling for Craigslist to ban all help wanted advertising to avoid murder?  If the logic they use is so sound than one would think they would be calling for ending all employment ads to prevent this kind of crime.  Except they wouldn’t want that in this case because it would seem stupid (because the logic is stupid) and would affect them.  But when it is sex workers they have no problem implementing absurd thought processes that affect us.Terrible crime but one would never consider ending help wanted ads.  Yet, for our work they immediately jump to that point and a majority seem to flow with that idea as logical.  Perhaps this analogy will make sense?  http://www.usatoday.com/news/nation/story/2011-11-23/craigslist-killings-ohio/51376280/1?loc=interstitialskip
