My opinion on if you’ve pre-paid is to use up as many resources of theirs as you possibly can in that period of time. Play (if you like), be active, be loud about things on the forums, etc. I am always in favour of getting what I’m paying for. I wasn’t playing a lot but I played some as my paid time ran down. I even logged in with 14 minutes left on my subscription to check the pet cage bug! 
If someone has paid and doesn’t want to play, I also get that. Still, I’m a fan of using the resources that paying the org grants me as best I can while I can. Even if it’s to make YouTube videos that criticize them.
