 Thanks for the block.  For some reason unknown, most of his/her vandalism was focused on me personally - the articles were listed on my user page as ones I had started, he/she took biographical information from that page, and added abusive comments (that I am "a taxpayer-funded Jihadist POV-pusher") to several pages.  I'm not going to get too upset about it (it's the first time I've experienced quite that nature of abuse, so I feel honoured!) but obviously further action will be needed if they reappear after the block is over.
