Huh? What's meant by that? Is it directed at maintainers of official LiveJournal communities, telling them not to delete them? Shouldn't such maintainers already be ridiculously aware of the fact that they shouldn't delete official LiveJournal communities? If that's what's meant... Does it really need to be there? The sentence was very abrupt and seems unnecessary.
On a sidenote... Shouldn't #16 link to #93 in its "further reading" section?
