Question 

Why was I banned from Wikipedia? please write me an email:
XtheBandit001@AOL.com 
i got the following message when trying to edit:
"This is your last warning. The next time you vandalize a page, as you did to Category talk:Suspected Wikipedia sockpuppets of WatchtowerJihad, you will be blocked from editing Wikipedia. A link to the edit I have reverted can be found here: link. If you believe this edit should not have been reverted, please contact me. Alphachimp talk "
By the way, I never joined that topic or even visited that page, so how could I be in trouble?
thanx
