I have had a @libero.it email address for more than 10 years. I stopped using it regularly when they disabled POP/IMAP for people connecting through other providers, but still logged in occasionally every once in a while.
Today I went there and my saved emails were all gone. Apparently I didn't log on for three months (which may or may not be), and this "authorized" them to go and delete all I had left there for 10 years.
This policy is braindead and guaranteed to piss off people. Storage is cheap; if they really wanted to "temporarily disable the account" (in their words), they could have simply bounced incoming mail, and compressed the few megabytes (!) of data, ready to be restored the first time I logged in again.
This act of destruction was unnecessary, and carries the risk of being sued by angry people. This is the sort of decisions that made Libero.it (once at the forefront of internet-adoption waves in Italy) a fringe player; while Google and others ate their lunch, they were all busy penny-pinching, pissing off old-time users faster than they were making (very few) new customers.
