Is that actually good?

While other people are not doing the effort. That's mean you have more chance to win, if you put in the effort for that contest. This type of event is better, because you can get more chance to win prize rather than a giveaway who are fighting against 2000 user.

In the contest only 26 comments. 20-30% maybe a comment word, 30-40% are people who put a random image without effort. That's mean you a real user who are putting effort only around 7-9 people, the odds win are good.
