You know how we're always remind you to update your privacy settings? Here's a great example why: If you try to hire a hitman on your Facebook wall, and your Facebook wall is public, you will get arrested.

This is what happened, at any rate, to Philadelphia mother London Eley, according to police:

According to authorities, Eley posted this message on her Facebook wall: "I will pay somebody a stack to kill my baby father."

Investigators say Timothy Bynum took up the offer.

"Clearly, if he would have received the money, he would have carried this out," Philadelphia Police Lt. John Walker said.

In fact, Bynum allegedly responded to Eley on Facebook: "say no more," "what he look like?" "where he be at," "need dat stack 1st," and "ima mop that bull."

We'd even go so far as to say that your Facebook wall is not a very good place to hire a hitman, or to discuss your planned hits. If you absolutely must solicit a hitman, just do what everyone else does and make a Craigslist ad.
