[WikiEN-l] Off-article linkspamming

[A]

I have noticed an emerging trend for linkspammers to spam their sites on
article talk pages, user pages and user talk pages, especially after failing
to get their spam placed in an article itself. [[WP:SPAM]] does not have a
clearly formulated policy on this from what I can see.

For instance, [[User:Hoodia]] was especially egregious today, spamming the
[[Hoodia]] article, but also setting up a User talk page that consisted
entirely of spam:

http://en.wikipedia.org/w/index.php?title=User_talk:Hoodia&oldid=94315565

This case is obvious and common sense, but I have seen more subtle issues
recently, such as this editor listing her site
www.BreastImplantAwareness.org/ after her signature:

http://en.wikipedia.org/w/index.php?title=Talk%3AStephen_Barrett&diff=93819056&oldid=93777864(scroll
to bottom)

Does this count as linkspam? It struck me and other editors as
inappropriate.

SEO spammers are going to want a working link from Wikipedia to improve
results, so I suppose <nowiki> is an option in many of these cases. As
another example, a longtime detractor of mine who was eventually blocked for
linkspamming still managed to spam links removed from various articles to
her bostonschoolofelectrolysis.com website via another editor's talk page:

http://en.wikipedia.org/wiki/User_talk:Alphachimp/Archive_7#PLEASE_REPLY_AND_EXPLAIN_YOUR_SELF

This is now archived and indexed on Google, effectively achieving the
desired result of a direct link from Wikipedia.

These phenomena seem like something we should address before it gets much
worse. I guess the most contentious one would be links to one's own sites on
one's User and User:Talk pages. I'm not sure how that line should be drawn.
A blanket ban would probably drive some editors away, and any policy would
probably have a lot of gray area regarding what's acceptable.
