Tell tale signs of fake?

[eques]

I've been looking at some of the Indonesian and Filipino swords on ebay. Some of the prices look attractive but nobody bids on them, which lead me to think if it was a fake (tourist item) or not. What are the signs that a sword is fake (tourist item) based on the pictures alone? Would one consider a lack of patination (on brass) or thin blades as signs of fake swords?

Thanks!
