I don't understand why theymos said there in that quote that keeping IP logs is extremely useful for account recoveries. Most hackers will just use Tor or a VPN to log in, and most people will also use VPN and Tor to browse this site, ...
maybe that's the same reason why theymos won't recover account easily
those people using Tor/VPN are hiding their real IPs, so theymos can't verify the origin of user
if the user logged from the same clear domain (non Tor/VPN) almost all his logtime, probably theymos would easily release the account
