It is terribly sad that it comes to this during and after every disaster, but there are criminal willing and able to take advantage of those selfless and willing to help. Please be careful when responding to requests for support and focus your energies on trusted entities.
It is sad that we have reached this point. Microsoft is now preventing online support ads in Bing because the high risk of fraud. I am sure other search engines will follow suit. This is sad because there are good platforms for providing sound online support. Users lose in this situation, but I think Microsoft is doing the right thing.
