Ahoyo, haven't used this site in a while, but I'm giving away a stockpile of older (and newer) keys! As far as I'm aware, all of these are not region-locked and should be usable (assuming my bookkeeping has been accurate)!

I ask that you allow me to delete just in case there are any issues (though obviously I can't force you to honor that. o.o)
