The only peeps who can remove an item just by a message to eBay for being fake are those under Vero regulations, read about Vero from a link at the bottom of most eBay pages.
eBay would never remove an item a member claims to be fake as eBay do not see that item, and the complaint could be coming from a disgruntled buyer, or even a competitor, this does happen.
Should a buyer buy a fake item they are guaranteed a full refund under eBay's 30 day MBG policy. If a seller is continually selling these items eBay take note and will take actions, restrictions or bans from selling.
