Anon user 89.130.28.68 behaviour 

Today when I woke up, I found a whole lot of personal attacks from anon user 89.130.28.68 against me.

Messages such as:
"THIS USER IS SUCH A STUPID AND BIASED WIKIPEDIA EDITOR. SHOULD BE BANNED FOREVER!" on my user page.
A blanking of my talk-page whith the following message "buaagh i'm sick only reading this user please..remove him from wiki!!!!".
"that is fucking stupid and haves no sense!!!! That is a person with various nationalities NOT A NATIONALITY OF SPAIN . ONLY MAURICE27 CAN SAY THAT!" in the Nationalities of Spain article.
"WTF!!! IS NOT POSSIBLE THAT MAURICE27 IS STILL EDITING THIS ARTICLE FROM A SUCH BIASED AND STUPID POV!!!!!!" in the Catalonia article. (NOTICE that I hadn't edit that article since January 17, 2009

I ask you if you can do anything to stop this kind of behaviour with a ban from a user who has been attacking me since April 2, 2007 and who I'm pretty sure is a sockpuppet from ).
