It won't be counted as most signature campaign manager will not allow it. And so with that the best thing to do is,
- post more than what your campaign requirements are, if it says 20, then post 22 or 23, it wouldn't hurt you that extra post. And it so in cases like this, post being moved to off-topic then at least you still have buffer post
- usually if the post is not gambling related, i.e. there are topics about some neighbors or friends getting addicted and asking what the community advises, then it should not be in gambling boards . Then think twice before replying as this might be moved by the mods or someone reported it as off-topic post
