Campaign managers have their assessment of the quality of posts that they will count or not count. If the quality of the post does not meet the standards of the campaign manager, it will not be counted. some managers exclude some boards that don't count. as well as the quality of participants' posts.
several other members have shown how many managers select new participants. maybe you can get better if you start to adapt. although each manager has their methods and standards.
Maybe the tags on your account can also be taken into consideration by the campaign manager when they want to see how you really are.
