I was one of non bitcointalk newbie accounts who participated in CoinDragon contests/giveaways. Your concern is nice but I doubt coindragon is making fake giveaway/contest since all entries are verified with the provably fair system. If you think that those accounts are shady because most of their posts are in Coindragon contest's thread, it is not a valid evidence to say coindragon is making fake contest/giveaway. Let me tell you, most of the contests by coindragon requires participants to post as many betIDs as possible to win the contest. For some people including me, it looks like a spamming posts and there is possibility that those mentioned accounts are just secondary/alt accounts of higher rank member in this forum. I was thinking myself to create a new bitcointalk account just for the Coindragon's contest in the past but I canceled it because I do not really like to participate on contest where the winners are based on the most entries. As one of early coindragon's players, I can say that coindragon is trying their best to give something back to players by the contest/giveaways. I dont see any reasons why coindragon needs to create fake giveaways.
