If you post 40 an hour, you will be marked as spammer ans got banned in less than a day. I think 40 posts a day is quite enough from one member, any more would raise some eyebrows. To be honest, there aren't that many serious topics a day to reply to.
That you make 40 post in hour isn't reason to ban anyone, if all those post are constructive.
this forum is very friendly and does not ban you if you make 40 post a day but main thing your posts are meaningful not trolling.But 40 constructive posts a day is not an easy task
