gm thanks for the doing the hard work of charting a path here! a few questions: 

1. what kind of tax obligations should the DAO expect? would auction revenue be taxable? And will the DAO owe any back taxes?

2. how will sanctions checks work for bidders in practice? typically this involves KYC, but the post seems to suggest that the check can be done post hoc via chainalysis? If so, what happens if we find that a bidder was in fact a sanctioned entity?

3. have we considered removing the fork mechanism and NOT replacing it with a refund? the currently proposed refund mechanism means that the DAO is effectively extending downwards price protection to bidders

2. AFAIK a check with Chainalysis at bid tx and reverting if the bidder is sanctioned should work
