User making personal attacks 

At the bottom of the Samuel talk page http://en.wikipedia.org/w/index.php?title=Talk:Samuel&action;=edit&section;=15 the user below makes personal attacks on another user. Below is the personal attack. he is also promoting an external site to further his personal attack on another user. Please help.   

If you look over the rest of that editor's contributions, as well as this site about his activities elsewhere, you'll see that that user is indeed crazy.
