Thread:User talk:Aaron Schulz/having issue with one of the pages about my work on polish wikipedia

Hi Aaron i wondered if you could help - one of the users has complete control on my polish version wikipedia page here and has a lot of wrong information up about me and my work. here is the page http://pl.wikipedia.org/wiki/Katy_Carr --- several people have confirmed the changes but he insists on putting the info back up to his original wrong version I wanted to ask how do i ask wikipedia to block a user --- this guy is intent on causing us great upset - this is the user http://pl.wikipedia.org/wiki/Wikipedysta:Pernambuko

hope you can help! best wishes katy
