Will leave you feedback as requested now
You shouldn't, unless you planned to give him positive rep in case of peaceful resolution (which I would have done, if I were you).
"Don't give trust to people asking for it" sounds like a sane rule to me, still.
+1 I have left him bad feedback for taking a trust loan and I suggest you do the same !!!
Warning do not trust zackclark70 he is a scammer and has now done a rep loan !!!!
