I know they were playing patch whack-a-mole already, but that is likely a contributing factor and certainly won't help if they were already suffering burn-out.

They wrote it wasnt related to a specific incident, but this is my theory too

They weren't accepting post-coinjoin utxos a few years ago, they would literally send them back if you tried to send them for lightning.

I assume they would do the same thing in this instance... Except it wouldn't be clear which funds were stolen that would come out later, and effectively be stolen property they would have no right to. Which meant they couldn't get anything for it and effectively operate at a loss...

A mess, really
