[GRASS5] wiki spam

[Hamish]

Hi, 
I just removed some invisible wiki spam from the main GRASS wiki page.

They create an account on a popular wiki site and paste in a huge list
of URLs to try and get their spam customers a better Google ranking. For
better survival these parasites use html codes that make the links
invisible to the casual user.

The offending user id this time was "VitSet"
  http://grass.gdf-hannover.de/twiki/bin/view/Main/VitSet

can their IP number be blacklisted? (mostly as a feel-good measure)
