Based on the admin's recent updates, seems we can still chat about mixer services and such, just not openly promote any specific ones. So if someone wants to have a discussion around the progress of mixer development or other privacy tools in general, that should be fine from what I gather.
Just trying to clarify because I want folks to feel comfortable talking broadly about technology while also respecting the rules against endorsements.
