Bro. If it were that easy to "force" someone onto DT, then scammers would have exploited the hell out of that long ago. The person who sent the feedback to you will only get on DT (level 2) if a level 1 DT member adds him into his trust list. Nothing you can do will force that to happen.

And if you didn't realize what the answer to your question was from what I said... no, I can't see it by default.
