In putting together documentation on Privacy & Security Recommendations, we wanted to express the safety in reusing shielded addresses while making it clear that users should maintain different payment addresses for contexts which shouldn’t be associated. It was difficult to describe clearly in a sentence or two, so we decided to write a blog post about the topic to fill in extra information.

I’d suggest all shielded-address mentions (in FAQ, privacy recommendations, blog posts, etc) include a short aside with “here’s an example shielded address (‘z-address’), in this case for [worthy ZCash-accepting cause]”.
An example of a z-address:
