Does LiveJournal delete accounts for inactivity?
No. LiveJournal will not delete your journal if you do not update it.
There are, occasionally, scams targeting LiveJournal users asking them for their login information by visiting a URL that almost matches "livejournal.com".
If you ever receive an email, or any other form of contact, regarding your LiveJournal password, please disregard it entirely, and certainly DO NOT click on any link provided.
LiveJournal will never contact you asking for your password. If you are ever asked for your login information, DO NOT under any circumstances disclose this information.
