This document acts merely as a guideline. Everything outlined here is in no way mandatory as it is a moderator's right to act according to their own ethics.
A warning will often suffice in these cases, however it is not mandatory conduct;
If you have broken a forum rule, this may resort in a short ban for one hour; even without a warning.
If a user repeatedly breaks the rules, then the moderator may extend the duration of ban to what they feel is necessary.
This can include: one day; two days; a week; a month or permenant.
It is important for a moderator to consider the context of the repeated offences. If the offence is of low priority, then perhaps an elongated ban would not be efficient.
Major offences are breaches of the rules that are of high priority. This includes: Impersonation; Flooding and Flaming.
When those rules are breached it is possible that a user will be given a harsher ban. This is in order to curb bad behaviour and deter frequent offenders.
Evading a ban will not be tolerated and will lead to a harsher ban in all cases.
