So you believe him to be a scammer for removing liquidity from the markets?
I'll detail it in PM when I get time to write it all up.
But in brief the summary would be that he scammed in various ways:
1. Deliberately misleading investors (current and potential) so that they'd over-value his securities. Clearly anyone who bought them based on false information suffered loss - as they paid more than what they would have had to pay had the false information not been promulgated (and they may not have invested at all had the false claims not been made - avoiding the inevitable loss associated with investment in usagi).
2. Using assets from one security to prop up another. That had the effect of transferring value from one asset to the other - defrauding all investors in the first (and enriching those in the second).
3. Removing equity backing a guarantee - causing a loss to a specific set of investors (this one's fairly tricky to understand but blatantly obvious once you figure out the math).
4. Extending an interest-free loan from one asset to another and disguising it as an investment. This actually defrauded a THIRD set of investors (sounds impossible - but true) rather than either of the parties to the loan.
5. Attempting to defraud investors of assets that rightfully belonged to them (this one's ongoing).
6. Repeatedly lieing about past events - defrauding anyone who believed those lies and invested as a result.
Note that none of these have anything to do with usagi's trading performance - that's incompetence not scamming and doesn't deserve a tag.
Note also that it is my contention that to be a scammer you do not necessaily have to succeed at scamming. If you intentionally make misleading statements with an intent to gain financial benefit (defraud) then you are already a scammer. If anyone then invests that makes you a successful scammer. So I don't believe there is any need to prove that any specific individual actually suffered loss - just that there is a class of individuals who reasonably could be expected to suffer loss as a result (whether any actually did suffer such loss is irrelevant).
The reason I say this is simple:
Say I offer an investment and make a false statement in the process of selling it (claiming expertise I don't have, claiming I have personal capital I don't have, claiming person X is a good friend of mine - whatever, it doesn't matter). IF the statement if proven to be false AND it could be reasonably concluded that the statement would increase the likelihood of people investing (by making the offer more attractive) then that should be sufficient on its own to award a scammer tag. It should NOT be a requirement to prove that some specific individual actually invested because of that statement. A lie was told to try to get investment - that's enough on its own in my opinion : it shows the person is a scammer, it's not necessary to determine how successful they were at scamming.
That only applies, of course, to false statements that would reasonably impact on people's decision whether to invest or not (and how high to value shares). Minor details such as gender and name would NOT warrant a scammer tag even if given in the context of soliciting investment. Repeatedly lieing about gender/name etc should, however, be taken into account as evidence that someone habitually lies and hence any unsupported claims made by them should be given less credibility than would be given to such claims from someone who had a record of usually being truthful (it's character evidence - which gos to determining the credibility of a witness).
EDIT: removing liquidity from the market was just part of my explanation of how potential victims go far beyond just those who directly invested. I have no intention of trying to claim losses or even particularly argue that point now that it's accepted I can submit evidence without having invested.
