Or it just gives you enough time to transfer the funds to an alternate account or buy things.
I knew you would say that. As a matter of fact once funds are in you paypal account you can transfer them to a second account or "buy things" as you say within minutes. All you need is a withholding of some minutes not one day.
1 day hold time will not prevent chargebacks one bit so I think this is just to give you time to "cash out" the paypal.
You are right, nothing prevents a chargeback. The idea is not to prevent it but to know how to fight it back an win it.
The only way to protect from chargebacks would be to hold for 180 days.
That's only partially true. American Express accepts chargebacks for 1 full year so if your buyer paid you with AMEX you could feel the pain for a longer period of time.
I think that instead of trying to trade here I will sell consulting services to people that have been scammed via PP reversals.
