Another question here, about the same dilemma.
I went to see if I could put a negative on Kano's trust measure, but it looks like it's based on how much was actually staked in the transaction. Which for me, was a little bit of 'dust', about $1.37 at today's rates. So if I understand correctly, this wouldn't have any measurable impact.
Its not, it depends on your standing within the community. In order for your trust ratings to have an impact on others (who see! your rating, not receive it), they must consider you trusted. Every member has their own trust list they can (and should) modify freely. If you never change anything about this, you are using the 'DefaultTrust' network, which is mapped with account with the same name.
Is there such a process as a 'class action trust adjustment'? So that someone, me or whoever, could act as a class representative ('dust' miners) and collectively adjust the trust amount by the total that was scammed? Because by Kano's own admission, that's 16 BTC ($50,000+). That would have a significant impact on his trust measure, and maybe that would compel him to finally (after THREE YEARS) start paying people the money owed to them.
BTW, the very moment Kano fixes this I will remove all my negative posts about the subject. He seems like a generally well regarded member, and I dislike getting down into the mud over this, but I do believe that people should be paid what they're owed. So if the trust factor were to be adjusted as I described above, I would like to be able to reverse that if/when he finally gets his **** together.
You can open a thread in scam accusation and ask for help from those more trusted than yourself. Make sure you read that sections stickies first as it will give you some good tipps on how to approach this. Others could chime in, but usually if you can present sufficient proof on behalf of the group that would be enough.
