Anonymity and Decentralization has its good part but also the bad part, as we can see right now with the whole "Russia is using crypto to bypass sanctions" thing: we can't have anonymity and decentralization without creating some new problems.

As you said, anonymity is a reality on the Blockchain; and finding indirect ways to combat fraud due anonymity (like curators creating bogus accounts just to curate himself, but being difficult to be socially active on all bogus accounts), while it can actually work, just put more pressure and create more paperwork to the honest folks that has to audit the whole thing.
