Why would you give a feedback to a user who you didn't have a transaction with?
Unless and until the person scammed, or did questionable things that might warrant a negative, you don't really have to give feedback to any said user.
Congratulations on making on DT2, nae the Cult of Laura. Fwiw, you don't need to have any P2P interactions on this forum to give out trust, so long as you have the right mindset and be a nice bitch to Laura and follow her orders, you'll do just fine.
