First off, SE isnt going to do anything about this anytime soon. It took several years of GS's monopolizing emp pin and leaping boots and peacock charm, to get SE to do anything about it. So we (the community) need to come upwith a solution that doesnt involve SE.
Since we (the NA population) is all but completly cut off from communicating with the JP population about things like this, any kind of solution is going to be only a halfways solution. And even worse, only a small portion of the NA population would even consider or care enough to help with a solution.
This leave us (I will probably never need an O kote, but I am willing to be part of a solution that helps my fellow shivans), with very few resources, and a big problem that needs a solution. In the business world, this would be called a lost cause, but I am certain we the people have the ability, and motivation to make a difference.
Sophus has an interesting idea, however there are a few flaws in it (no offense, just gonna blurt out my opinions here). First off, blatently manipulating the AH system, is in violation of the ToS. Now the chances of anyone getting banned for it are virtually nil, but I say be the "Better man", and do this without violating any rules.
Second problem is, that the GS's have a near infinate supply of gil. Yes you may cost them some for a short time, but as soon as you stop manipulating the AH, they will be free to set the price at whatever they want again, which will likely be even higher, due to the gil they lost. So you would need to not only change the last 10 sales, you would need to continue to monitor the sales, and be ready and willing to readjust the price at any time. But thats not even the biggest issue. Lets say 10 of us were in cahoots on this. We list one, and as soon as it is listed, we send a /t to our partner, and they purchase it right away for the price that was previously discussed. This will show on the price history, but when the fat wallet player, or gil buyer goes to buy one, and sees the last sale at 4Mil, he/she will bid 4 mil. Then 4.5, and finally 5mil (or maybe even 6 or 7 mil). Since they have very little concern for their gil (if their just rich, or a gil buyer it wont matter much to them), they will keep bidding until they get one. Wheather it is 4 mil or 6 mil, soo many people have the "I need it now" attitude, that they wont wait for the price to drop back down to get it. So while you did change the price history, there are still going to be O kotes listed by the GS's, that will likely sell for the price they listed it at, which then takes all the time and gill you spent on changing the price history, and ruins it, and makes it esentially worthless.
So what is the solution? I have no clue. Haveing a group of people come together, and try and out camp the GS's sounds like the most plausible idea. But to make a real difference, you need a lot of people willing to spend a lot of time for virtually nothing (and we all know how much people are willing to do for nothing in this game). Spoofing the price history could work but I feel it would be temporary. Complaining to SE is virtually worthless. Anyone else with any ideas?
