Xbox has revealed a new system that takes into account the number, and severity of player infringements, as well as how the enforcement teams take action against these reports. The new system relies on strikes, which any give player can accumulate based on the weight of each infringement.
As explained in the detailed announcement on Xbox Wire, each number of strikes will get the player banned an appropriate amount of time. For instance, two strikes will earn you a one-day ban, and four brings that up to seven days.
Acuminating eight strikes will get the player in question banned for a whole year. The ban prevents you from accessing social features, like messaging, parties, party chat and even online multiplayer. You will not lose access to your purchased content, except in extreme cases where Xbox has determined there is illegal activity involved.
