It's a shame. I've used him once for escrow in the past and it was slow and he never lived up to his end (but did send the funds after a delay). One side of me wants to think that he wouldn't scam (being so involved in blockchain), but the other half of me realizes that a large percentage of early adopters are scammers.
What's more puzzling / a bigger mystery is why would he return the 1000 forum coins but not these 100. It doesn't make sense.
Does he have any other money still held in escrows?
