The interesting question is what will trigger a "blacklisted coin"? how many spend transactions before exchanges cannot afford to blacklist a coin linked to a previously conjoined UTXO?

I personally think that it will be unstainable to enforce in the long term, and in the meantime, I keep on conjoining and telling people to do the same.

Anything. It's probably up to the exchange. 

I believe I've heard this has happened before, but I don't remember the details.

A CoinJoin is a Political Act

> Although CoinJoin works quite well in many aspects, there is one big problem to be solved. Centralised exchanges such as Binance, OKX or Kraken may be required by the authorities to blacklist coins that went through a CoinJoin process.

I always wondered: What happens if such blacklisted coins are moved onto an exchange? Do I get a notification that I can't sell them? Can I just withdraw them again? Or what exactly happens?
