Hi AKPT,
I would partially agree to this since I'm not sure what actually you intend to say by saying this. Disagree/ Dislike option should be there but it shouldn't relate to the points system again .
Other than that, when you hit Disagree/Dislike to a comment, there would always be arguments over this. Since in SAP, there are many out there (with the experience & data) who would claim it to be true or at least not false.
Therefore, the motto behind it may not put the desired impact but too many new discussions in the SCN.
This is surely required but need to implemented, if considered, very carefully.
