Well, the system is actually pretty well made. Your IP is tracked. Checking the history of the Wincustomize entry, I saw the IP address of the person who created it (since it was as you said an anonymous entry, otherwise I would have seen his username). Then checking that IP, I saw that you also created the Windowblinds entry, and I would have seen any other activity of yours as well. Second, there are discussions for every entry, and a person can request that an entry or a whole article be deleted. For example, if you look at this article: http://en.wikipedia.org/wiki/Livingod , you'll see that it has been requested to be deleted and there is a discussion about it. I think it's well organized so there is very little abuse, and when there is there are ways in place to deal with it.
