The day you got serially upvoted (yesterday - 28-06-2013), your reputation was 232; 200 from regular upvotes, 2 accepted answers and 2 reputation from accepting an answer. You hit the daily rep cap. After this happened, somebody started serially upvoting you; so, you didn't earn a single reputation point from those upvotes.
The automated script, having detected such serial voting, simply reversed all the upvotes. As you hadn't earned any reputation from the serial upvotes, you didn't lose anything when the action was reversed.
Disclaimer: I am saying all of this by looking at your profileprofile.
