Well if I were one of the participants in your campaign that manage by you and received a message like this, I will consider this as a warning and will never do it again. This means --I joined the signature campaign that is managed by you so it means your rule will follow. Your campaign, your rule. Not all managers have the same criteria for checking posts, so if you have been warned, you need to change your posting habit even though consider it a quality post.
However, this is not a big deal if you will follow the rules even if that is a burst post or not ^{[at least you have been warned]} --or leave the spot that you have.
