Surely karma will take care of these folks.
There are reports (and maybe you've seen the posts) that people on Facebook and other social media sites are claiming to be storm victims when they're not. Those folks are asking for money right along with legitimate hurricane relief efforts, generating sympathy, and in some cases making a buck.
In the 1985 we had "We Are The World". Last year it was "We Are The World 25 for Haiti", now we have "Songs For Japan", an album where the proceeds will go to help relief efforts in Japan.
