For me, the campaigns are totally fine as they are already, provided that:

1. no rush.
2. no minimum posts to get paid.
3. no mandatory posting in specific sections.
4. no need to change posting habits.

When I started co-operating with icopress (approx. 1.5 years ago), he always did the work like this.

Now, I co-operate with Royse who also does the work like this.

I 've expressed multiple times that:

A. I won't change my posting habits for a campaign.
B. I won't post in gambling section for any reason.
C. I won't go into a posting-spree just to get paid.

As long as the above criteria are met, I believe that the signature campaigns that follow them, will always shine among the others.
