From the old patch notes:

New Infraction system.
Infractions replaces bans on "entered sgtools protected giveaway without a valid entry" cases. This new system will use a strikes based calculations to ensure that a user is really aware of those infractions before being permanently denied of getting thought sgtools giveaways.

Strike system details:
1. First Strike -> 1 month
2. Second Strike -> 3 months
3. Third Strike -> 6 months
4. Forth+ Strike -> 3000 years (aka perma infraction).

Users currently serving an infraction will see a red bar on the top of every giveaway-related page informing of the time it'll expire. They can do every operation on sgtools apart from qualifying for giveaways and getting the url.

There is still permabans in place (currently only 5), for the following cases:
* Users that misuse giveaway feedback to bypass giveaway rules
* Giveaway url leakers
* Trying to exploit in any other way the system
