Yeah I think this could help , if you won't be able to meet up with the post count of a campaign then not applying seem to be the good idea but I don't think it really works..., currently you can only get picked in a campaign  if you are well qualified  and even if you're qualified, you still have to compete with other that are as qualified or more qualified  in making quality post than you.Getting picked makes you privileged over others(i mean no one will like to give up that becauseof the post count), now the need to adapt to the boards for required posting  arrives and most campaigns are gambling... thus, you not been qualified as a shitposters depends on who..  and how others see your post , some see gambling posters as shitposters and trully there's high percent of .... there actually.
The forum is actually broad, just make your post and try not to make it shitty  .
