Recently, a hot network question lead me to this SciFi question Why are there so many 47s?. Some of the highly upvoted comments on both the question and the answer encourage other users to try to vote the posts to a "perfect" score of 47. Examples:
Are comments that encourage this kind of improper meta-voting and not actually for the standard reasons of usefulness and clarity not constructive and should they be flagged as such? (Currently, both the question and answer have a score much higher than 47).
*Disclaimer* I am not a member of the SciFi community and do not know the voting culture there specifically. I also cannot flag the comments without becoming a member.
