Minimum 35 posts per week? Isnt that too much and it will influence the quality? Also they payment amount is not as high as in other campaign (but this is not my business).
Last question - who is holding the funds? Escrow? Im asking that because that influenced a lot on bestchange signature campaign. They didnt use escrow and BM got a negative trust for a period of time... as well as some people abandoned the campaign because of that.
