I've experienced it, my post is very complete that is 15 posts per week, but every week my post is considered half and token distribution to me is different from what they promised.
after that off I'm all trying to be patient, and again they make trouble by not putting their coins in the market. I have their coins but I can not sell them!
me and a group of my friends try to deport the people who run the project, let them get negative !!
Most campaigns have a requirement that the 15 posts are 'constructive'. This means that short posts that don't really add anything to the discussion or issues with grammar or wording might not be counted, thereby reducing the number of tokens you receive.
Based on the wording of your thread, I'm guessing english is your second language so that might be part of your challenge in getting your posts considered 'constructive' by the campaign manager.
Most bounty campaign managers are open to questions, so you could ask why you haven't received your share of stakes/tokens. My guess is that it relates to their decision around 'constructive' posts.
