Why care about an activity rating, a forum is for discussion, not a score competition. Just be active and your activity will grow. Be patient and please just post for contribution to the forum, not for your activity score.
Because they don't understand the way the scoring system works, newbies spam in hopes of getting their rating up and/or they've joined some newbie signature campaign and think they can earn a fortune by blasting the boards.
What the system really boils down to is this: at some point your post count MUST be equal to or greater than your time score to earn the highest possible forum rank.
Examples:
User 1 posts 1 post every 2 weeks. He joined 2 years ago. He has a potential activity score of 728. His actual score is 52.
User 2 posts 14 posts every 2 weeks. He joined 2 years ago. He has a potential activity score of 728. His actual score is also 728.
User 3 posts 100 posts every 2 weeks. He joined 2 years ago. He has a potential activity score of 728. His actual score is also 728.
User 4 makes 1 post today. He joined 2 years ago. He has a potential activity score of 14. His actual score is 1.
So what this means is If someone makes even 1 meaningful post per day he's gonna become a hero in 2 years irrespective of all the useless posts that he's made over the course of that time Or he might get banned because of those useless posts that he's been making for the past two years...
So far the best post that helped me understand the essentials of activity and posts...
