ebay has very strong policies against these types of communications. a friend of mine once sent a brief note to the seller of a 100% certain, known fake. my friend sent it through the ebay system; the seller reported him to ebay; ebay sent him a "nasty-gram". I imagine ebay would consider it an even worse violation to communicate with bidders.
bottom line: the most that we can do is hope that people read this forum or other websites before they place their bids.

: When we find that the consensus of our esteemed
: opinion indicates that the watch is an
: obvious fake, should we tell not only the
: seller but also the bidders? How about
: notify EBay too? If we notified the bidders
: it might tend to cut down on these fakes if
: we can dry up the market for bidders through
: knowledge.
