I haven't investigated this yet. That's why the title is "investigate?".
This is just seeing what other people think to find out if it is worth investigating.
So far all my points have been dismissed..
In terms of input from Fluffy, he is welcome to answer my above questions, this is an open forum

That is really shitty man. We aren't children on the playground gossiping about each other. Why would you post on the forum without first talking to the person you are accusing and asking them wtf is going on? You are no better than every fucking whiteknight SJW posting on tumblr. People like you make me sick.
Grow up and stop acting like a kid. Just send the dude a message and tell him what you're worried about. Are you so scared of him that you're posting this shit on a forum thread first? Coward.
Hi - no disrespect, but what exactly is Fluffy's word on any of this supposed to prove? If my concern is a structural problem with Monero that is unhealthy and I ask him if he's using that to gain market info and then trade big on Poloniex where volume is all locked in and he says "oh no, not doing that" - then I shouldn't have posted this? And he's free to come here to discuss, why do I need to contact him privately?
EDIT: again, I am not trying to single out Fluffy here and attack him. I am saying MyMonero / 95% Polo volume seems like a bad idea basically because it *enables* someone to take advantage and undermines the core selling point of the coin, I don't know if anyone is doing that or not.
