Today, I got 3 downvotes--two were within a minute of one another and the other was 3 minutes later. At the same time, my profile views went up by two. While three downvotes at once, where I only have a total of 21 posts, is strange, all within 4 minutes seems suspicious. That my profile views went up by two seems to indicate that someone used my profile to browse through other posts of mine to downvote, which = targeting. I am fairly certain all of these downvotes were by the same user. While I am fine with losing 6 reputation, I definitely think that such behavior is unacceptable and is a detriment to the site.
For reference, please see this question on downvoting etiquette.
