Using the fee system can be exploited, just put another, identical item up, and wait for your item to be returned (so rather than selling a 99 stack of an item, sell a 33 stack, if that's undercut, put another 33 up, and another undercutting each time, once one hasn't sold and is returned put it back up.)
FFXI's AH was extremely easy to manipulate, showing a history of I think it was the last 10 items sold, you just need to either out some up for 1 gil (or your own price) and buy it back, do this 10 times and no one knows the current value of the item, to make people not realize you are manipulating the AH you could get friends and LS members in and all buy from each other.
The only defence against manipulation of the AH in FFXI was the fact we had FFXIAH, they had to get permission off SE to poll the AH (anything else and the only way to do it would to have a bot scanning the AH, which was against ToS) so unless SE allowed it in FFXIV that would not work.
The fact is when you have a player controlled market, people will always find ways to undercut and manipulate the market, no matter what SE does.
