Same email arrived too many times

I received 7 identical emails both to my email address and my inbox here on this site. As you can see from the times, they all arrived in a couple of hours. All of them encourage me to make something for the Lights contest, but one would be enough! :P
This has already happened before with other "You might be interested in this contest" emails.

Maybe you have entered the contest multiple times in the past. I got repeating e-mails and messages as well (though not more than two per contest)...
