Was that a list of *all* tokens, or just a list of "significant" tokens?  I
don't use the web interface, so I'm not familiar with it.  By default,
spambayes only pays attention to tokens with a spamprob less than 0.4 or
greater than 0.6, and most "display the tokens" gimmicks have defaulted to
showing only the tokens that went into the score computation (== only those
with "strong enough" spamprobs).  If you made up some obfscuated Subject
lines, it's quite possible that the unobfuscated words simply didn't show up
in your training data often enough to get a spamprob significant enough to
show.  I judge stuff like this by looking at the Outlook addin's spam-clue
report's "All Message Tokens" section.
