I can’t be bothered to link to all the livejournal clones which use the same text as livejournal, but be assured they’re out there. Also, diary-x used to have one, but their entire site is basically destroyed at the moment after their server went kaput with no recent backups, which goes to show that even non-serious contenders think it worth their while to have some form of contract.
