Yes, you're right, but there are forums that pay members to post, and sometimes they take measures like subtract money from your balance if you have a long period of inactivity, honestly it's something I don't approve of, because people can have different reasons why they can't participate in the forum, and they don't have the obligation to communicate it as the staff members would, in short, it's something that doesn't help the forum at all and only causes stress in the users and probably discontent.
