InsaneJournal Announcements

Why is this affecting communities? I was under the impression, after the last username purge, that this sort of thing only affected individual accounts. I know of several communities that I was a member of, which apparently are now being purged, even though they have posts that I participated in and would have liked to continue to have access to in them. It seems a bit inappropriate to be doing this to accounts that have actual content in them. Empty journals, I have no problems with, but deleting things with content in them? What if you delete the journal of someone who's deceased, where it's one of the last tangible connections their friends have with them? I really think that's wrong on a huge number of levels.
