First, I would like to say thank you, as the League of Legends subreddit always has tons of giveaways, which is super generous and super awesome.

Second, I would like to suggest that if you do a giveaway where people just have to participate (post any comment) in the thread to have a chance, that you should take a look when you select winners. I was thinking you could take a look at their account to see if is a legit redditor or if it's someone's throwaway just for another chance to win. I feel like it would have no content (posts or comments) other than for contests.

TL:DR People with multiple accounts ruin giveaways for people with only one account. Make sure a legit account wins your giveaway (or don't I guess it's your giveaway).
