I noticed some vandalism on http://wiki.rubyonrails.org - hard to spot
vandalism where just the link destinations have been changed without
altering the visible page contents.
For instance this page
http://wiki.rubyonrails.org/rails/pages/HowtoChangeSessionStore
was vandalised in this version:
http://wiki.rubyonrails.org/rails/pages/HowtoChangeSessionStore/versions/52
But this version is ok:
http://wiki.rubyonrails.org/rails/pages/HowtoChangeSessionStore/versions/51
I am reluctant to revert the page to version 51 and to lose all the
legitimate changes since. Is there any way to just remove the bad
changes?
And a wider question, is there a way this kind of pernicious vandalism
can be prevented?
