This is the kind of misleading title that the media shouldn't print. This guy was actually recruiting on behalf of ISIS and bitcoin was just incidental to the story.
Sure, this headline draws more eyeballs to the article, but the editor should think twice before clearing a title like that.
True, I bet people have sent money to ISIS using all sorts of methods including Paypal, but I have never read a headline about someone helping ISIS with Paypal donations. Twitter is full of accounts promoting ISIS, but you don't get the media blaming Twitter. It's a cheap sensationalist headline and t's not going to put people off Bitcoin because people will see through it.
