A week ago, we made a few minor changes here, most notably a switch to Jetpack Comments. Since then, spam has dropped dramatically. Prior to the change, we received an average of 10,000 spam comments a day. After Jetpack Comments, we have received a grand total of 429 spam comments for the entire week. So, that’s a drop from an average of 10,000 per day to an average of 61 per day, 9,939 less spam comments per day.
