I also think that this is not a proper signature campaign that everyone joins with full heart anyway, this is like the place you go to for in between situations, your last signature campaign ended? You are looking for a new one? Well get this one meanwhile and then you can end up with a new one and carry this until that day. In this case, being paid is enough, since it is a very tiny amount that they are paying as well, it is never a problem for me.
If that's how you use the campaign, no wonder you say that. This is not a campaign to be in just a couple of weeks. On the contrary, it is a campaign to stay in for a long time. It is the longest running campaign in the forum and precisely the structure of tiers what it does is to encourage people to stay. I am in tier B Mr member. If I make all the posts in a week I earn more than $50, which is in line with most campaigns of this kind. Although in this one you have to write more posts.
If you only use it between other campaigns, you will be in the lowest tier which only pays you a few satoshis.
