So it seems that old accounts are deleted after half a year (?) of inactivity.
This is understandable since we need to keep the database clean.
But can we at least differenciate a little bit and be smart about cleaning up? If someone spent a few months playing a game and then disappeared - sure, delete the account in half a year. But if someone's been playing for several years, maybe give him a longer grace period? There are not that many accounts who's been around for years, we can safely keep them for a bit longer.
I think it's obvious that preservation (or the lack of thereof) of the old account can sway the decision of a potential returning player.
