I was working on sending a proposal with a user on this site and today, I saw the other user was banned but now the pening cart is stuck as a cart in progress but I cannot delete it because the site says I cannot correspond with a banned user. 

Hi, for some reason the same thing hppened to me.

Hello,
 
Please indicate me the username of the suspended user, I'll delete the associated cart.
 
Thanks,
