Some posts really do not count, if they are too short, or do not make sense.
Now they can be taken into account if temporary organisms for some ranks are not sustained, namely:
For Beby Steps, the number of messages will not increase after 40 messages, unless seven days have passed since the account was created.
For the junior member, the number of messages will not increase after 130 messages, if 30 days have not passed.
For a full participant, the number of messages will not increase after 300 messages, if 60 days have not passed.
