Spammer 

Hi there.  For future reference, when you see a spammer or vandal, you can warn him/her using the warnings found here: WP:WARNINGS.  After they have been warned typically 4 times and the behavior continues, you can go here: WP:AIV to report them and potentially get them blocked.  Look over those links, and if there is anything not clear, or you need help at any time, post to my talk page.  Thanks so much for your interest in helping curb spamming here! -
