The Wasabi report from Europol gets instantly deleted as soon as it's uploaded to any of the file-sharing services. Someone doesn't want it to be out there, it's now deleted from the CoinDesk article as well. You can still read it here: https://t.co/8iKPfI0Bc7

The EUROPOL document was published in April 2020 (for law enforcement only). According to the paper if you properly mix via Wasabi, transaction can't be traced. One reason for EUROPOL trying to hide this publication.
According to Ivan on Tech it might be possible that some services identify Wasabi Wallet Addresses and block your transaction. So far nobody has heard of major exchanges blacklisting Wasabi coinjoined addresses.
