The tour page (successor of
/about) contains a section “Ask about…” and a section “Don't ask about…”. The positive section lists the main topics that are available on this site, but the negative section contains only the default boilerplate.

The format constraint is that the section has to start with “Don't ask about…” and needs to be pretty short. Most sites use a list of bullet points.
