LJ purging inactive communities and accounts.
excerpt: EDIT: Purging inactive accounts: One of the benefits of the work we've done to purge suspended accounts is that we will now be able to purge inactive journals and communities too--something you've been requesting for years! A journal is defined as inactive if it has not been logged into for 24 consecutive months and has only one post (i.e., the welcome post). A community is defined as inactive if has not been updated for 24 consecutive months and has only one entry and no comments. Once an account is eligible to be purged for inactivity, the owner will be sent an email to alert them of the inactive status. The owner will then have two weeks to log into the journal or post to their community to prevent it from being deleted. If the owner does not log in or post, the account will be deleted and treated like any other deleted account (the owner will have 30 days to log in and undelete the account to prevent it from being purged). Purging inactive accounts will take place sometime after we've begun purging suspended accounts, probably in late August. Again, you can read technical details about suspended and inactive account purges in this post. We'll be sure to let you know when these purged usernames become available
