Yes, the admin's clarification can clarify whether services like Jambler are included in the prohibited category or not.
It looks like a "NO" according to theymos's post, although he said
probably and the user who ask it mentioned URL link(s).
Would it be OK to have a signature linking to a blog/article explaining what mixing is, how it works and containing URL link(s) to mixer(s)?
It'd be OK in a post. In a signature it would probably not be allowed, as it would look like "promoting a mixer".
Because I see there are still users asking about this;
@theymos
What about a service like Jambler.io? Does it fit your definition of a mixer or advertisement for mixing?
It doesn't link to or promotes a specific mixing service, but promotes a way to create a mixing business. Based on your rule update, talking about mixing won't be prohibited.
Please let us know.
and there are still those who have doubts regarding sponsorship of an event.
OP I see that voting is going to be open for 60 days, but better beware of the new rules starting from January 1st, and I am not sure that main sponsor is going to be accepted than.
Big purge is coming.
So the admin may need to add additional explanations in the new rules regarding mixers later, like the one you quoted above, maybe in the FAQ category.
