Some users post many entirely machine-composed answers, e.g. integrals computed by Maple (e.g one user has over 150 such answers).
Should such "answers" be CW?
Should they be comments?
Update ($2$ days later) $ $ Based on initial feedback in comments, answers (and downvotes), it seems some readers may have misinterpreted the scope of the question (which I thought would be clear from the many linked examples).
To clarify, this question concerns only answers that consist of a computer algebra system command followed by its output (the "answer", e.g. here or here). In particular this question does not concern answers that additionally include proofs or explanations of the way the answer was derived (be they human or machine generated). There is no intent to discriminate against machine-assisted answers (having been a Macsyma developer I have much respect for such symbiotic collaboration).
Note that if someone wanted to gain rep quickly for nefarious purposes, then this loophole provides an easy quick method for doing so. Even a user with little knowledge of mathematics can feed these problems into a computer algebra system - even a bot could do so.
