Oh, an infraction is this:
Get two and you get banned depending how long the infractions last.
Basically...its like advanced negrep that if you get two points you get banned.
If I gave you say, 2 infraction points that lasted 1 week, you would be banned for a week.
But I only gave you 1 infraction that lasts a month. So if you got an infraction you would be banned until one of the infractions expires.
