To block another Discogs user to contacting you :
- From the drop-down menu on the top right of your screen, next to your avatar, select Settings, then Privacy.
- Scroll down the page and add the username(s) to the Blocked Users field.
- If the user later changes their username, it will be updated automatically within this list as well.
Please note: Blocking another user in this way will only prevent them from sending private messages. This user will still be able to place orders from your inventory. If you would like to block a buyer from purchasing from you, please add the username to the list at the bottom of the seller settings.
Also, if you're having trouble with an existing order, please contact Discogs support.
