I was searching Google, and found a website ( http://tramadol.tfres.net/wiki/Main_Page) that, when visited, loads a live page from Wikipedia, and puts a large number of Google Ads at the top of each page. According to a relevant page on Wikipedia ( http://en.wikipedia.org/wiki/WP:FORK#Remote_loading), this, and the irc channel #wikimedia-tech, is the place to report this.
I first reported this on #wikimedia-tech. The first reply said to just "post to mailing list", while the second said to go to bugzilla. Is this the right place?
[attempt 2, hope it gets through this time]
