I see! I haven't tried it myself, but it would be interesting to know whether blacklisted inputs are marked as such / if there's any GUI for it or whether users just get a (presumably) generic error message. In that case, your experiment may even have been the first case of Wasabi blacklisting reported on the forum.
It wasn't blacklisting because I tried the same thing with bitcoin testnet network and it was not working as well.
Maybe it was related with some Tor network issues related with ddos attacks, or some other unknown issue.
I used wasabi v1 few times before, and it was working fine without any issues.
Not to get too far into the weeds, but there's very little trust required to use bisq other than having to trust that selling bitcoin for fiat won't result in a charge-back. But that requires trusting the other trader, not the software.
That is still trust, and you need to trust Bisq software is doing what it says, unless you know the to read the code yourself.
Than you also need to trust other people if you are doing p2p trading face to face.

You are not really turning off and hiding anything by switching off your modern smartphone.
