Frea.cc email is powered by a company called everyone.net. Unfortunately it would appear they are no longer loving the free email model. A number of users are finding their accounts locked and support are saying they will only unlock the accounts twice before permanently locking them.
If your account is locked permanently then you will lose all of your emails. We suggest you move your email to gmail, and set up a forwarding address from your frea.cc account to a gmail account. That way, even if you continue using frea.cc, if something happens your old email will still be available at gmail.
For more information on how to switch go to gmail.
