Nothing special. SpamBayes is trained by an individual, according to

There is no collection of random words that has a good chance of
fooling many SpamBayes installations, and it's particularly difficult
to guess an individual's "ham" words.

I don't really know what you mean by "selfless spam", or by "nonsense
words". If they're legitimate words, but more or less chosen at
random, then that's often called "word salad". If you mean gibberish
strings of letters that aren't really words at all, then SpamBayes
scores them at 0.5 (exactly halfway between ham and spam), as it does
for any word it hasn't seen before. They don't affect the overall

Neither word salad nor gibberish (pseudo-)words are effective against
SpamBayes in general.
