The problem is I just got a 2 point decrease in rep without it showing up in my activity summary (and it's not the first time).
Could this be as a result of a flag as spam on one of my posts?
If so, this behavior could potentially be exploited, as I don't think this will show up in the anti-vote-fraud script, and furthermore, there's no way of knowing which posts are being flagged.
Could we at least add the rep lost as a flag to the envelope summary as a way of alerting us?
If I hadn't been on the site at that moment, I probably wouldn't had known.
