I’m a bit concerned about my contests because I am noticing quite a few entries from the same IP address with different names and email addresses. I hate to believe that people would cheat on book giveaways in which I am donating my own books and shipping money, and it discourages me from wanting to do more of these kinds of things in the future. If you think this post might apply to you and you can provide some explanation, please contact me and let me know what is going on. Otherwise, I will plan to disqualify multiple entries from a single IP address. Of course, that does not apply to comments for extra entries based on tweets or blog posts.
