There are a couple reasons a spammer might do something like this... one
is to probe for valid addresses. However, it would be completely
ineffective as a tool to poison bayesian filtering databases. These
filters work on the words that are in the mail, not on the words that are
not in the mail. So including words that are unrecognizable can have no
adverse effect on the database, or the filter's ability to recognize spam
based on the content of the database. In fact, an additional filtering
technique could easily be developed which would create a token based on
the number of words that are NOT in the database... so they're probably
shooting themselves in the foot...
