As the seller, i need to pay middleman fee 1st, isn t your policy

Yes it is strange and it's a scam. We do not charge middleman fees and we would never email you this.

Do you use K,I,K, Skype, or another messenger service?
No. All middleman transactions are done through PlayerUp.com for security reasons. Anyone who attempts to contact you through a 3rd party messenger claiming they are us is fraudulent.

When should I release my account information to the buyer?
Never release your account information unless (@Middleman) contacts you through the PlayerUp Conversation Ticket System. We will never contact you through e-mail, K,I,K, skype, or any 3rd party service. All middleman transactions are done through PlayerUp.com for security reasons.
