Stop Craigslist From Allowing Advertising For Animal Abuse

Based on a very disturbing article I read about 2 men who advertised for sex with animals on Craigslist.  There is evidence to suggest a Middle School Teacher named Mr. Trejo had placed an ad on Craigslist to find a dog owner that would allow him to have sex with their dogs.  I feel there should be kind of monitoring of what is allowed to be advertised, abuse in any form should never be allowed!  There must be a line drawn at some point.  I think it is in poor taste and judgement to allow abusers to look for victims so easily as to post an ad on Craigslist!  I would hope the CEO of Craigslist  will take this seriously and make some adjustments that will filter out any questionable content placed on his site.
