No escrow will accept this trade for all the reasons listed here. It just means the escrow would lose money as well as the btc seller. Unless you're willing to wait a year for the funds to be released (as there is a time limit on payment reversals). Nobody reputable is going to take the trade, as many people have been scammed by this in the past.
To be quite frank there is actually no need if I find the seller to be reputable enough. Escrow is just more hoops to jump thru for this simple transaction & tbh I'm so sick of reading the word scam. What has this world come to where everyone wanting to buy something online via paypal is auto labled a scam artist?? It's ridiculous.
Why are you so insistent on PayPal then? It obviously gives you protection but whoever you buy off has zero defence if you reverse the payment. You're the one being unreasonable if you cannot see this. Nobody is labelling PayPal users scammers - just PayPal users who want to buy bitcoin. You're "new" here but you'll soon learn that nobody takes these trades for a reason.
