[Systems] Clearing wiki spam

[Bernie Innocenti]

Frederick & Luke (the mediawiki experts I know),

we have a spam problem with the Mediawiki instance of Paraguay Educa:

  http://wiki.paraguayeduca.org/index.php/Diario_Sugar
  http://wiki.paraguayeduca.org/index.php/Calendario_Laptops
  http://wiki.paraguayeduca.org/index.php/Calendario_Educacion
  ...

What's the most effective way to get rid of it?
