So let me get this straight - you used a mixer, the mixer mixed your coins exactly as they said you would, you deposited your coins on a centralized exchange, the centralized exchange decided to lock your account, and so you post a warning about
the mixer?

Your mistake wasn't in mixing your coins - your mistake was using a centralized exchange which attacks the very essence of bitcoin by treating it as non-fungible, by discriminating against certain coins, and by censoring certain outputs.
Why is no one questioning this? In what other scenario would this be even remotely logical?
I sold an old laptop to a friend for cash. I used the cash to pay a builder who was doing some work for me, and he disappeared without completing the job. Therefore, beware of selling things to my friend!

I traded cash for bitcoin using Bisq. A scammer on Telegram then convinced me to send them my bitcoin and I lost everything. Therefore, beware of using Bisq!

It is Uphold that you should be posting warning messages about, not any mixer. Uphold are the ones who are spying on your coins and locking your account.
I had to quote the whole paragraph because the logic of the argument is impeccable.
The only question I have for you and those of you who know more about the subject is, to what extent is the excuse that they give that they are simply doing it to comply with the law true? Even more so when they say that according to privacy and confidentiality laws they are not going to say anything more on the subject. On top of that I see that the Uphold company is based in London, which is the money laundering capital of the world for large amounts of money.
