My thread is clear, he tried to scam me and forum escrow is expensive and takes forever to organise, while bitify takes 2 minutes to make a listing and send it to the other party to make payment.
Idk if he's a scammer or not, but next time you do a trade you should put your feet in the shoes of the other person too. Since you both didn't know each other, he felt and thought the same way as you (unsure if the service/payment will be delivered). Having a trusted escrow involved would be the best solution in such cases (I doubt that it will take forever).
