If you do not follow all 4 steps you will NEVER be added back. This helps me filter out spam accounts. I also don’t check comments on screenshots. All communications is through this account.

1. Add me as a friend.
2. Click on the Trade Link above.
3. Choose one of my items, leaving your side empty. (Does not require mobile auth confirmation)
4. Leave a short message in the trade message similar to a comment.
