What you say either don't make sense in relation to the fact that all users were allowed to withdraw 6.17% of there Weexchange balances, so possibly Ken Slaughter(that we know that SEC have been looking at) and Trade Fortress for example could have withdrawn funds then to.
Ukyo said he allowed the users to withdraw the ~6% because he
believed it was the right thing to do. The word "
believed" makes it sound like he got into some trouble for dispersing those coins.
Did he open for withdrawal of the ~6% again btw?
Source:
Are you able to say where the available coins came from btw?
yes but he wont

Kanoi is correct that this get's into issues where I have to tread very carefully. Those were paid out because I believed it was the right thing to do.
