POY is probably the most prominent example of what I was cautioning 
about.  Of course, you can look at the sequences and then feed them 
into POY, or even take a second look at anything that places oddly 
(especially if different genes are giving different results) after you 
run it, but I am aware of a few curious results that came out of POY 
due to bacterial or otherwise anomalous sequences that were supposed to 
be molluscan.
