If anyone should get tagged for this it's the ripple developers for promoting a system which automatically treats even explicitly worthless debt as having the same value as payable-on-demand debt. Sounds like they intend to fix this - but it's hardly a new issue or one which they were unaware of.
And people handing out ripple trust for no reason is hardly new either - as soon as ripple was launched there were threads where bunches of idiots handed out trust at random to one another.
These are actually very good points.
