Try doing “chain-analysis” yourself, find a transaction and trace it through the blockchain on mempool.space

I am not an expert on the subject, but I would say to be safe that the wallet is “tainted”

For example if I had any of the transactions to the wallet, I would be able to see any outgoing transactions as well, if the output is going to a mix/coinjoin- I would lose the ability to prove where they went- but would be able to know that it was mixed.

Again, not an expert- recommend looking up some privacy tutorials or hopefully someone more knowledgeable can tune in here. 🧡
