Hello list members,
Today I noticed on
http://wiki.rubyonrails.com/rails/pages/WorkingProfessionallyWithRails that
there were a ton of spam links in the source code that I couldn''t see
on the page itself. Upon careful examination I found the links to be hidden:
I am posting the content here for reference and to show patterns of spam:

This is really bad from search engine optimization post on view and can lead
to penalization of ethical sites that are linked from the page.
How can we watch for this spam?
May be a filter is needed that checks for the existence of
"display:none"?
Or may be all links need to be converted to rel="nofollow" which
will then not benefit any link on that page.
May be we need to make the wiki posts for registered users only.
Now I also suspect that such hidden links may exist throughout the Wiki.
