So. I don’t want to talk too much about this one. Both “Mahodara” and “Wu” clearly want to keep their circumstances hidden. And I’m in the practice of keeping confidences. You all trust me to keep what I know about you quiet, and so I’m going to keep pretty quiet about everyone else, too. 
Here’s what I’m willing to say:
“Mahodara” is on the wrong side, but everything I’ve seen of him suggests that his heart is in the right place. It’s not a question of whether you trust him, but whether you think he’s even in a position to do any real good.
As for “Wu…” They’re clearly not being up-front about stuff. Not being totally honest. But from what I’ve seen, they’re only hiding the truth to protect themself. I don’t think they’d betray you.
That’s just my opinion, though. Keep working on this yourself and you might come to a different conclusion. And don’t be afraid to contact them directly; they both have accounts that can take PMs on this board, although I’ve done my best to make sure they can’t read anything.
