Account trades and other digital goods is always risky to trade since they can be claimed back by the original owners.Escrows won't help much if that happens.Yes,the big 10 list doesn't guarantee they'd be online all the time or even escrow such risky sales.Meanwhile,you can use other alternatives on basis of their trust and forum reputation.The problem is ,no trusted members are willing to take a risk so I doubt it will be of any help suggesting an escrow for you.Message him

I also think Escrow favors the original owner in case of physical and digital products, as owner can claim it to be not valid or faulty and thus keeping the goods plus the payment.
I think there are many paid Escrow on this forum and you can find the best one for you in Services Sub-sections.
