Actually, I think spreading around false panic rumours about things that other folks actually find useful on a regular basis is not a good thing - I read that post you linked, and the poster admitted to not even testing all that much before their panic-post.

Dude. You should hear me cuss when some person or another whose journal I want to search to find *that one thing I really want/need to find* has turned the ljseek searching off. Seriously, unless it's states or personal secrets and the poster is not wise enough to f-lock right off the bad, ljseek does no more harm than google (the satan) which I might also point out *also* caches the pages it parses. But we don't see any options to lock out search-engine searches, do we? *huffs*
