AccountKiller
The sentence we don't like about the FAQuestion on deletion is: "However, you will need to manually delete any comments or entries you posted in other journals/communities." That may be a lot of work!
This means a completely automated deletion is impossible. Anyway... Be logged in, use the link to delete and deactivate your journal (account). You have 30 days to undelete your account. Also read http://www.livejournal.com/support/faqbrowse.bml?faqid=16

Publicly visible text/images often aren't properly deleted even when you succeed in deleting an account. Try editing or deleting them manually before deleting the account itself. If you're unsure what happens to your tracks you can always contact LiveJournal and ask personally. By the way, deletion requests don't necessarily mean your data will actually be deleted (e.g. due to legal obligations).
If you signed up for LiveJournal using a third-party login such as Facebook or Twitter, you probably want to revoke all access from LiveJournal. Click the icon below to find out how.
