Possibly some of your old posts god upvoted in the mean time.
God does not have an account on LW yet. Unless you were speaking metaphorically?
God wouldn't need an account to upvote. It would require less total divine intervention to just flip the specific bits where the vote totals are stored.
Presumably, God wouldn't need to upvote; it would be more effective to simply induce the desired behavioral changes directly. Though that would admittedly be more distinct interventions.
At the moment my karma is 450 and -50 for the last 30 days. I had never 500. Also not a month ago.
Must be a bug in the karma counting system.
