My reputation appears to have increased for some reason today. I first noticed a jump of 200 reputation on January 18 in just 10 minutes, but assumed it would be soon reversed. I noticed another jump today from votes within a 10 minute time range - just 20 minutes ago, but the previous votes from January 18 still have not been reversed.
I have not answered any questions for weeks, and generally only get some stray votes from old answers.
- serial upvoting that doesn't look like serial upvoting to the automated script?
- or something that is not serial upvoting, but looks like serial upvoting to me?
