Being GetThere (eyancy) has posted here in this thread, they are quite obviously aware that their data is being accessed in a manner in which was not intended (by unauthorized users). Perhaps after becoming aware of KVS and their methods they're easily tracking as the methods change and shutting them down as fast as KVS can find an alternate way in. Not a very user friendly way of trying to get your data if you're constantly needing to update the application, and may find yourself not able to get information during a time of need. KVS in my mind would be so much better off to create a new level of the tool where the data is being paid for and accessed legitimately, as ExpertFlyer does, even if it means the user needs to pay more for that version. I know I personally would not be interested in a tool that needs to be updated every few days just because the tool needs to constantly find holes that haven't yet been plugged.
