In summary, the report concludes that these transactions were likely intentionally filtered by F2Pool, This raises the question of why F2Pool, a pool with origins in Asia, is the first pool to filter transactions based on US OFAC sanctions, especially considering that other transactions with similar or lower fee rates were included
And in typical American fashion, American companies may be given a no-gag order, obey quietly or else...
So you can just choose what State will enforce their rules, depending on where the pool is.
Unless some pool starts operating in the "dark web" (tor hidden/i2p, etc) or such, with anonymous use like ckpool does for solo. But what if those operators do a rug pull? It happened in the past in the clear net...
Maybe a REAL pool operated in El Salvador or some country favorable to Bitcoin? (not a whitelabel from yet another American company).
Funnily enough most OFAC sancitoned transactions that were dropped by F2POOl were mined by the Foundry Digital. The private close ended pool that runs exclusively for an alliance of north American miners that are to a large extent U.S. public companies. I guess this is just by chance mostly since these guys are the biggest pool lately, but it goes to show that at least for now, FEDs haven't cared to force any miner's hand at enforcing their censorship list on miners and mining pools for bitcoin.
Although it's a very real possibility, I don't think the laundering happening through bitcoin is significant enough to warrant the government's attention to that extent. They'd waste too many resources and anger a community that's quite big so they've probably purposely avoided this. Or they've just not gotten around this yet. Probably good idea to not have good faith towards FEDs.
