You are promoting mixer services , which are not legal
It varies based on the jurisdiction and the specific regulatory framework. They are not illegal everywhere.
Do you explain somewhere that these services are based solely on trust
I very much do. I'm right as well recommending coinjoins and XMR swaps if trusting some stranger is enough of a concern, both of which are not illegal and might provide even better levels of privacy and anonymity. I guess you have a problem with that either.
and any use of those could potentially lead to loss of funds or even legal problems in the future ?
As I said, I do point out that mixers require to forfeit custody, so loss of funds is a potential scenario. As for legal problems, using a mixer isn't illegal anywhere that Bitcoin is legal last time I checked, so no I don't believe there are legal problems with owning mixed coins.
So , you are using propaganda ( look at the definition again ) , as you are biased and have personal gain . Is it so hard to get it ?
Isn't it much of a cheap excuse for all of you who aren't wearing a signature to blame the personal gain when arguing about mixers? We can eliminate mixers entirely and opt for XMR swaps (which, by the way, I'm not being paid to promote!), but you would still need to explain to me why desiring these levels of privacy is inherently wrong.
