Not sure about RICO, but I think wire fraud charges would apply:
"Wire fraud occurs when a person intentionally and voluntarily uses a communication device that sends information over state lines as part of a scheme to defraud another out of money or other valuables…creating a webpage to ask for donations for a charity or a personal tragedy that is fraudulent.
A person charged with wire fraud can face a separate charge for each act of fraud. For a single conviction of wire fraud, you could face the following penalties:
Prison sentence of up to 20 years
Fines not exceeding $250,000"
