It seems automatically generated comments such as this:
Does this answer your question? Ramsey-Turan number
don't include the user's ID number. As I understand, people can earn the "Announcer", "Booster", and "Publicist" badges through people clicking on links with their user ID. A highly popular feature request Reward finding duplicate questions - +10, +2, -5 (plus a gajillion duplicates) ask for some reward for finding duplicates. In principle, it's possible to edit the comment to include one's user ID, but in practice, it's too much of a hassle to be worthwhile.
I'm just wondering if there's a reason why it's not designed to automatically include the user ID, to help them earn these badges.
Question: Why doesn't the "Does this answer your question?" duplicate link include the user ID number?
I understand the comment is auto-deleted if the question is closed as a duplicate; perhaps this is the reason.
