Although I posted this in another thread, some people have problems finding the correct page specifically for reporting fakes.
(You will be asked to log in if you aren't already)
1. Click on the following link:
http://pages.****.co.uk/help/contact...e=Continue+%3E
2. Change the **** for the word e bay (without the gap in the 'e' and 'bay')
3. Change the .co.uk to .com or whichever extension is local to you.
4. Once on the page click on 'E-mail us' and on the following page type in the number of the item you wish to report, which can be found in the top left hand corner of said auction.
A sticky for this might be pretty good considering it's much quicker and easier to report them this way rather than burning lots of time clicking through the options on the 'community' page.
