Hi,
if you want to take this 1 step further, you can charge for membership, and remove anyone from your group who doesn¡®t pay. You could give a discount to ?contributors¡° (those who post) or grant free membership to them, based on the activity log.
But I consider it my own private business when I read a message/contribution or if I ignore it. I would consider an automatic check a breach of privacy.?
WhatsApp has such a mechanism, but that¡¯s a chat system, and even there you can decide not to make that information visible to others.?
