I continue to quote the post where I traced the Whirlpool transaction you provided because people need to be aware of the transaction links created by Whirlpool coinjoins that can be avoided by using WabiSabi coinjoins.
No. You're continuing to quote the post where an individual consciously decided to consolidate Whirlpool coinjoin input with toxic change. I have used Whirlpool with Sparrow, and I have never had my toxic coins consolidated with my coinjoined.
If the given exchange does not require the KYC procedure to go through out, why not.
The answer is as simple as "because it isn't designed to do it". Exchanges share tons of stuff, which user owns which addresses, trading volumes, etc., with governments and chain analysis companies. As I've already shared, there's even a site[1] which takes as input an address and returns you to which exchange it belongs. It's also more expensive.

What does the fact that I'm wearing a signature with MixTum has to do with me recommending people to not use exchanges as mixers as they aren't designed for that?
If you could read Russian I would refer you to the real life case when user used exchange to clear his coins he got from dedicated mixer.
There are no "tainted coins". There are only tainted businesses. Ratimov uses a lot of exchanges which don't treat bitcoin as fungible. You shouldn't be using an anti-Bitcoin service in the first place.
