And spoofing is possible because people don't filter.

from unless you can either log it at its source or trace the stream to its
source. That's the problem, and filters don't fix that.

So we shouldn't filter at the source because we can't fix the problem unless
we're filtering at the source?

Or are you saying that because seat belts fail 1% of the time, we shouldn't
use them to help in the other 99% of the crashes?
