  This is your final warning. You will be blocked from editing the next time you vandalize a page, as you did with this edit to Network effect. J.delanoygabsadds 23:01, 8 March 2010 (UTC)Reply

 
You have been blocked indefinitely from editing for continuing to add spam links. Persistent spammers will have their websites blacklisted from Wikipedia and potentially penalized by search engines. If you believe this block is unjustified, you may contest the block by adding the text {{unblock|Your reason here}} below, but you should read our guide to appealing blocks first.
