When searching contains an artist tag listed in the APL (avoid posting list), display a status message, stating that said artist doesn't want their art displayed

Such a message will help users to differentiate between an artist having no posts because (no-one has added them before) VS (the artist doesn't want them to)
Currently: If a user doesn't find their favorite artist listed, they are likely to try to post some of that artist's work, without checking the APL first.

The status message section of the Results page will be affected by this change

This is how I would imagine it being displayed:

Note: The artist's name uses a <span> tag, not an <a> tag, with the CSS modified to style it
(by adding "span.tag-type-artist").
This is because we don't need to link the artist tag, as it'll just lead to an empty results page
