You don't have to be a DT1 member for your feedback to be visible for the general public. You are part of the DT2 network of users and that makes the trust ratings you write to others equally visible on the forum. Your feedback doesn't appear under the 'Untrusted feedback' section on the Trust page as it appears for users outside of the DT network. You have removed the feedback mentioned in the OP. Good call! Case closed!
