I've only known him in this forum, where I've been very grateful for his contributions. He's provided a lot of valuable information, backed up by evidence and links to various resources - often stuff we would never have known if it weren't for Hazim. His opinions seem to be based logically on real evidence, so worth reading.
By his own admission he has been a bit naughty occasionally in his youth, but never wicked or malicious, from what I gather.
So. yes, if he provides a viewer which he says is compliant with LL's ToS and the TPV rules, I'd be inclined to trust it.
