It all depends on the requirements of the campaign, because posting requirements change from campaign to campaign. Some campaigns might exclude posts being done in specific areas of the forum, example : Games & Rounds, Investor-based Games, Lending, Auctions, Meta, Politics & Society, Beginners & Help, Off-topic, Archival, Local.
Some might say that your posts length must be, say a 100 characters minimum and your post was shorter or you posted more than the post limit per day. <They do not want people to post all their posts in 1 or 2 days, they want it spread out over a week>
Just read the rules of the campaign and you will spot the reason for those posts not being counted.
