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.
I'd say if there's a user who can their posting habit because of the campaign they joined, actually the campaign isn't for them since they're honestly not meet the whole criteria.
or leave the spot that you have and find another manager.
This is what the solution is or just simply not try to join the campaign, but as we know there's many users are really want to get money even though they need to become a completely different person e.g. the one who regularly post on local language and not a gambler, but the campaign doesn't count any post on local language board and need to post in gambling section.
