Hi John,

Here are my comments for your reports and questions.

No, they don't.

Because they are not "text describing the destination" as written in SC
2.4.5. Additionaly, they don't address the intent of the SC which says
"The intent of this success criterion is to help users know where a link
goes, so they can decide whether they want to navigate there." These
links don't help users to do it.

They can be accessible as the users can understand where these links
would go even though it would take longer time for them to "decide
whether they want to navigate there." In my opinion, however, I don't
think that WCAG should recommend "accessible, but not usable" things to
the authors. WCAG is really influential guidelines all over the world.
If we admit these ambiguous links, there can be many web pages with a
number of "more...", "click here", "here", and so on. The users would
have trouble navigating web pages. I don't think this is what we want.

If the author want to use "more..." or "click here" as a link text, we
should recommend to add the title attribute describing the destination
so that the screen readers could provide the additional information to
the users.
