[CMake] Wiki spam

[Johannes Zarl]

Hi,

I just noticed that some spam pages seem to have been inserted 
into the wiki using these user accounts:

http://www.cmake.org/Wiki/Special:Contributions/Carinsurancecarinsurancequotes
http://www.cmake.org/Wiki/Special:Contributions/Sarawilliam30
http://www.cmake.org/Wiki/Special:Contributions/WalterMosley
http://www.cmake.org/Wiki/Special:Contributions/Janyrobert23
http://www.cmake.org/Wiki/Special:Contributions/Rozer456
http://www.cmake.org/Wiki/Special:Contributions/Jason85clark

Also, one can find lots of spam pages via the orphaned pages...

Is there a preferred way how to deal with wiki-spam one encounters?

Kind regards,
  Johannes
