So if they've decided it's spam, what's the problem with throwing it

The same problem as always: False positives. While I think the various
admonitions we have in various documents that try and discourage silently
dropping messages are unrealistic, the fact remains that silent draps
create
reliability issues. Rejects address this issue and are preferable, as
long
as they don't create additional issues.
"Spam" filters might include virus scanning, too, and the false positive
rates on virus scanning have gotten totally out of hand in the past year
or so. This is not a trivial matter; the kind of content that triggers
false positives in the AV scanners tend to be the kind that users get
upset over when it goes missing, e.g., compound documents, spreadsheets,
and PDFs.
