Why is Justin Sun a Scammer and Tron a Fraudulent Crypto Project?

Anyone who is active on this sub knows there is a great disdain for Justin Sun and Tron. With the sub frequently comparing Sun and any projects he's involved with to things like Do Kwon/Terra Luna, SBF/FTX, and CP Zhao.

Yet unlike the names mentioned above Tron continues to move in and out of the top 10 crypto projects by market cap and Justin Sun continues to grow his Crypto empire with frequent news stories about large purchases of ETH and other crypto assets. Obviously not collapsing (yet) doesn't mean Justin Sun isn't a scammer and Tron isn't a fraudulent project - it just means it hasn't collapsed yet.

So the question is why is Justin Sun a scammer and why is Tron a Fraudulent Crypto Project? What hard evidence exists, what is just circle jerking, and what is simply speculative concern?
