There are a few other bloggers that have addressed cheating on their giveaway entries. They have found numerous cheaters by checking IP addresses. Some have even gone as far as only allowing one entry per IP address per giveaway in order to put an end to cheating on their blog.
No one has named names yet, but give it some time, perhaps cheaters will be revealed.
This makes me wonder about my giveaways. This will NOT be tolerated and if you are in fact a cheater, please play FAIR.
