How do you ban a peer from seeing your trades using their onion address? Do you have plans to put this in the UI? Sometimes the other trader takes either too long to pay or wait until the very last minute.
Personally, I would prefer to not trade with these individuals since if I am not around the PC when they chose to confirm they made payment of the trade but leave only 10 minutes to respond. I will risk loosing my deposit since it will go to the arbitrator.
