I am against anything that could potentially put coins into limbo and add even a hint of centralization to the mix.
plus, there is no way I would trust any organization to decide how "tainted" my coins were ... it sounds like it could be ripe for abuse
Agreed on both count, but ... read my previous post: there nothing
you can do to prevent this from being built by someone at some point.
Actually, the concept being described is completely against the Bitcoin design.
The design is of course that when a transaction occurs, it cannot be reversed.
End of story.
As soon as that is no longer true you have destroyed the Bitcoin design.
It is no longer decentralised - someone now has power over it.
If 'some' central authority has the power to deem coins good or bad, then you may as well just dump Bitcoin.
Unfortunately sometimes people hack into other people's access security information and are able to steal what is protected by that information.
That certainly does not mean we should consider giving power of Bitcoin to anyone in any manner whatsoever.
That is purely a knee-jerk reaction to the problem - and should never be done.
Of course everyone has the ability to track down the path of the coins and then possibly confront the perpetrator and request them to return the coins.
However, giving that power to any particular person or group to decide is ludicrous.
If that is what you want - then go visit SolidCoin2.0 and stay away from Bitcoin.
