Plarium do well rewarding forum users.

They used to reward forum contributions each month or so but not so much anymore.

I love the Hearts for gold! competition. There is a good amount of gold and resources on offer. Also it encourages users to look at posts.

While I expect many people will skip down the post to the area with the information, a lot of people will read the full post as they are already there.

Plarium could make it a  monthly forum event and give away different bonus items each month. e.g this month is gold and resources, next month could be bronze, totems, scrolls & coal. The month after could be warriors drafts, soul shards, defence reduces etc.
