It's two different arguments discussing buying on FABO and selling here. With reference to cammers who SELL on FABO: Those of you who are "cash only" have no recourse to the seller who gives you (the buyer) nothing or not what you thought what you were buying. It would be idiotic to put cash in an envelope and mail it to a stranger. Walmart and western union are the same thing as sending cash. Paypal does tend to favor the buyer over the seller so that's the time to use it. Regular credit cards if the buyer will take them can do chargebacks if the seller rips you off. Postal money orders are harder to get back on a fraud claim. It's important to look at the sellers background and don't spend more than you can afford to lose.
