why using #fundraising websites instead of a simple paypal account?

I’ve just found out this gofundme online fundraising website. And I was asking to myself why in the world one have to use a website that charges a 5% fee for each donation… Is a paypal fee more expensive? It seems that they charge a 2% fee.

I can’t figure out why using fundraising websites instead of a simple webpage (like this, free, simple) and a payment way like paypal.

Could someone help me?

We ‘ve had an Earthquake here in Italy … and I think it would be good to raise funds for Emilia Romagna’s people … are there taxes problems? Or something else?
