Well hell they are put on FB for just about everything else so why not? If your dumb enough to give to them, then you deserve what you get.
There is a local news story a guy in a wheel chair got hit by a F150 crossing the street and the truck took off and he may lose his legs. He could walk but not real well I forget the disease the news said he had? But anyway there are two "go fund me accounts" on FB one them is up to 21K and the other 5K. It looks like the 5K one may be fraud?
