although i joined the forum at the stage when merit system is he guarantee for your ranking up, I feel that it's what is best for a forum as this. Let's assume you just need an activity of 100 to rank up, it would be very difficult for bounty managers to select those that they will accept no a particular campaign since the number if persons ranking at the same page would have been much.

But using the merit system, you can easily access the quality of a particular users post by going through his merit history and checking the post that ranked him up and it's going to be easy to know those that spam the forum and those that don't.

I feel that the challenge is that the number of merit source might not be all that much and sometimes ranking up might not necessarily be all that easy but the fact that quality threads gets you merited help one to out in the effort to making contribution that I of high quality and that can help some users that comes across your thread or replies
