Yeah, and me, if doing a fulltext search on 100,000 messages takes more
than a fraction of a second, something's quite wrong.  Responsiveness

Of course they would.  They're already running on hijacked systems,
using botnets to send out spam: why would they care about using up a lot
of somebody else's CPU?  They already don't care about using up a lot of
somebody else's network connection.

Yes.  Recommendations are all well and good.  There's a difference
between a recommendation and a should, though.  If I say, "I really
liked this restaurant: they had wonderful seafood," that's different
from saying, "You should go to this restaurant: they have wonderful
seafood."  The first is a statement about how you interact with the
world.  The second is rather rude if you say it to someone who's
allergic to shellfish, or someone who for religious or dietary reasons
must abstain from seafood, or... etc.

This is a meaningless question, because it presumes there's a single
objective standard for what is "safe and sane."  There isn't: all
security decisions are context-sensitive.
