I think a more concerning question is “should we be worried about what we post here?”
Bitcoin is not illegal and neither are Bitcoin mixing platforms, no one should feel they are doing something shady when interacting with any of them. So, no, we should not be worried about what we post here.
Of course if you're sharing illegal content and violating forum laws and government laws, such user should be worried, but others should be allowed to interact freely without limitations.
This is as long as the bitcoin is not illegal and the btc mixing platforms. What if a country (or a number of countries) passes a law banning this? I understand that users from these countries will have problems, but if something like this is adopted in the country where this forum is hosted? Will the forum have to constantly move from one country to another?
New changes in the world have begun. It seems to me that this precedent from ChipMixer is a serious reason to think about what the future holds for everyone and what can be done about it. In terms of penalties for the use of mixers and their use, as well as advertising on the forum.
At the moment, the issue raised by OP for discussion in this topic, I consider resolved, and there can be no question of any ban on advertising mixers. Because from a legal point of view there is no violation of laws (as far as I know). If there are any bans, I'm sure the administration of the forum will react to this.
