I also lost all my old Yahoo accounts because I didn't log into them for >1 year. Same for a lot of videos I made on a nice little site called GoAnimate. So keeping data is better than removing it! Even charging a fee feels fair-ish.
But forcing me to sign up for a subscription on an account I don't actually even have any data? Weeeelll, this doesn't feel so nice :)
In theory a copy of the emails are on a harddisk, but its control board melted, and when I got the same model disk (to transplant its control board onto the disk with data), I couldn't find the original disk...
