Despite not posting in several days, and none of my recent comments changing points, my points are mysteriously increasing at a steady rate
Worried bots have figured out how to game the system etc
Time passing and upvoting by you adds to score slowly. So rate of change might be interesting, if it is non linear perhaps you could snapshot your comments posts and upvotes and see if your bot theory is visible as very old posts and comments being acted on somehow.
I just upvoted this post and your score was 819 beforehand.
Did you comment on a story that went into the second chance pool?

Sometimes it can be a few days before they pop up on the front page and people see your good comments. Good luck.
Maybe you got better at posting? :-)
Maybe someone upvoted one of your earlier replies. It happens.
