Ghost is pretty clear on their signup pages. For example, if you go over your traffic limits:
https://ghost.org/pricing/
> Average views per month
> Views refer to the number of requests to your site each month. These are tracked much like an analytics 'pageview' - and are incremented with each page or API request.
> We never disable sites for traffic spikes, so no need to worry about the front page of Reddit or HN. If you exceed your limit consistently on a 3 month rolling average, we'll just let you know that you need to upgrade.
And for staffing:
> Staff users
> Staff users refers to the total number of active team members invited to Ghost Admin whom you collaborate with. For the purposes of billing, we only count staff users who have logged in at least once in the last 30 days.
> If you have lots of authors of posts who are not logging into Ghost Admin on a regular basis, they won't count towards your plan limits.
And if you don't want to upgrade they tell you how to avoid it before charging.
