I zoned out for a while and now have a lot of pages of unread messages.  I wonder if this kind of website would be considered a Mixer.  It might fit 1c from the modified OP but maybe it does not.  I do not understand 100 percent.

What if a Service pops up.  They take your Bitcoin and send you a Monero Private Key.  It looks like an Exchange but it is not.  They never call themselves a 'Mixer' nor do they seem like one at first glance.  The functionality is exactly like Chip Mixer but the Currency you receive in the end is not Bitcoin but Monero instead.

But the Service has two sides.  The first side of the website where they take Bitcoin and give you Monero.  Then there is another page where they take Monero and give you Bitcoin.  When you enter their website there is a clickable link for Privacy Enhancement where they provide tips for who wants to use their rights to Privacy.  They do not advertise themselves as Mixer or Privacy Enhancement tool but they advise to swap between Bitcoin and Monero regularly to keep up with their Privacy.

Is this considered a Mixer or does it avoid the definition and implicitly the ban?
