The answer is not the courts. SE is a public company, and the only people they answer to is the shareholders.
If there is enough backlash that this goes mainstream public and it causes the shareholders to lose faith in the earning potential of the company and inturn lose faith in their return on investment, the stock will become devalued, costing SE millions of dollars, a negative reputation in the stockmarket, etc.
remember, SE does not own SE, the shareholders do, and alot of those shareholders are probably customers.
so when it comes down to it, its up to sites like this, and others to spread the news, and keep it spreading until shareholders realize that they may lose money on their investment due to noones fault but SE's management.
My guess is the board of directors or even senior management have no idea what this crew is doing, keep in mind, there are very few of them and I wouldnt doubt they are in a small room in the basement. But if their actions are brought to the forefront and it is realized that their actions may actually and will actually hurt their future cash cow ff14, dont doubt for a second that this team will be on the receiving end of the ban hammer brought down by the board.
So if you want to send emails and letters, dont send them to the the ffxi team, that does nothing, of course they going to hide them, ignore them, its basically sweeping things under the rug so that their superiors stay uninformed, so if you going to write, write to the main corporation, to their public relations dept, if they get enough response to warrant a review from the board, we may be able to find sundi on an unemployment line where he belongs.
