What "watch list"? Using ANY mixer definitely WILL put your PUBLIC ADDRESS in a watch list in a database somewhere. Using a centralized exchange could possibly do that too.
The Bitcoin blockchain itself is a massive database of all transactions that have ever taken place and all the addresses associated with these transactions. By spinning up your own full node that maintains a full copy of this database, you are essentially deploying your personal watchlist, which you also can use to surveil brazenly the transactions and addresses of others.
About WasabiWallet, OP's concern is "taint". Wasabi's developers make sure that all UTXOs that enter their pool don't come from questionable sources. They merely want to protect their users from taint.
Apparently, the taint of bitcoin addresses is a flawed and misleading concept, and it largely depends on who you ask. For example, according to my standpoint regarding this concept, each UTXO that comes from Wasabi CoinJoin is to be considered "tainted" because, before entering the CoinJoin process as input, it had been touched or filtered by the dirty hands of chain surveillance companies. Therefore, not only did Wasabi not protect the user's from taint, it made all their bitcoins even more tainted and disgusting.
Plus you make newbies believe as if those users in your post are "scammers", but in fact you are the one who spreads disinformation in the forum and gaslight people. But if people trust you, then they will learn the HARD WAY.
I can also deem your post about taint disinformation, but, in fact, it is just a difference of opinion. If someone considers someone's opinion to be a guide to action, they should learn the hard way.
