Upvote pattern on this is odd. Is someone botting the votes on selected submissions?

Submitter has a karma score of 1 but there are, as of writing this, 37 points on this post and it's only 45 minutes old.

A similar pattern to https://news.ycombinator.com/item?id=42348956 which has 39 points after 15 minutes, and karma score of 1 for the submitting user.

Is someone trying to manipulate the rankings? Either upwards by points, or downwards by penalty.
