No, very unlikely.

Others may have a different view, but my thinking is that anyone still waiting to hear back from sugarfreedaddy who used PayPal goods and servcies should consider opening a dispute and immediately escalating to a claim. Anyone who paid with F&F should see if they can initate a chargeback with their bank or credit card company.

It's a diffuse situation, but at this point I recommend what @wont says.
