OP_RETURN threat and coinjoin trace

Two on-chain observations from 5 August by the analyst whose mapping graph is held at profedustream-mapping-export. First: the address holding the largest share of the stolen coins, given here as 562 BTC across 498 transactions, received an OP_RETURN message reading "I know who you are now" and "You made this bed for yourself, A."; the post links the transaction and asks whether it is a bluff. Second: it traces roughly 65 BTC taken from 465 addresses into a Wasabi coordinator where that input made up about 93 percent of the round, and argues the result identified the output address, mixed only 10.6 BTC and left that output's privacy weak because it was over 37 percent of the mixed coins. The 562 BTC figure matches the largest of the four consolidation addresses in the held Galaxy flow-of-funds post. Both readings, the identification and the conclusion that the operator was incompetent, are the poster's own and are not verified here.
