How to blacklist buyer/seller on P2P?

You can blacklist the buyer/seller by clicking on their merchant's Icon on the P2P Options page to go to the merchant's homepage.

Alternatively, you can click "Order History" on the P2P trading page and enter the dialog page to blacklist the buyer/seller.

How to check those who have been blacklisted

You can manage your blacklist by clicking "Mine" on the P2P page and selecting "Follow/Blacklist" after going to your homepage.

Note:

After you blacklist those users, they will not be able to trade with you again or send messages/calls.

Blacklisting will also hide these users advertisements. If you want to trade with them again, you will need to remove them from your blacklist first.
