[DIFE-256] Automate the ban of spamming users

🎩 What? Why?

In order to detect those users, we need to define behaviors we want to prevent.

Rules:

○ Allow 3 posts per day for citizens that have no post in the last 6 months ○ Allow 10 posts per day for citizens that have at least three posts for more than one day and less than six months old ○ Allow 25 posts per day for citizens that have more than 20 posts in the last six months and older than 24 hours ○ Allow any moderator / admin up to 100 posts per day ○ Inform any user that exceeds the quota that they did so and ask them to come back in 24 hours (this will be as an warning message)
