FYI, it's controlled by option minimum_prob_strength.  You can arrange to
ignore nothing by setting that to 0.0 (the default is 0.1), or to ignore
everything by setting it to 0.5.  Almost all testing reports said 0.1 worked
better than 0.0; one report did a little better at 0.0, but, for the reason
you gave, a setting of 0.0 would leave an exploitable hole in the scoring.
As is, gibberish words have no effect on scoring, but do have a subtler
effect:  they bloat the database size.
