I admire the desire for adapting the signature campaign to the forum needs. Not many services tent do do it.
You made some good changes like keeping the minimum required posts to 10 and paying per post which just reduced the HQ spam which gives you a better reputation.

I don't want to be pushed to post just because I'm missing 4-5 post. Ideally the signature campaigns shouldn't change the posting behavior of the participants, but this of course is almost impossible as many users are here just for the $.
Anyway, you can make it a bit more flexible if you want. Like the participant can choose to wear avatar or not, many people prefer to keep their own avatars and have only signatures on for reduced reward of course.

Sometimes you see participants from the same campaign in a discussion and it's a wall of all the same avatars and signatures and for my opinion it doesn't look very attractive, but again this is just my opinion.

The content of the posts should be more important than the number of the posts. Of course, every service wants a better exposure but the practice have shown that those who hire posters just to reach the weekly quota are not taken very seriously. So you are heading towards the right decision.

The CM campaign has put the bar very high but it's a good example how a sig. campaign can be successful in a long run.

Good luck to your business.

The campaign was in OPEN status for a whole week, but you decided to apply exactly after the onset of CFNP status.

Yes, that's right, I was promoted to Senior member on September 17 and I immediately applied for a bounty Signature. And in this list, BestChange Campaign in the status is open ..

Thank you very much for merit and for your advice! 
I have written to the Manager and hope for a little indulgence for me.

Hi, Best_Change. Thank you for another great week. Today I received a new Hero member rank. May I apply for a new position in the spreadsheet?
