For the first violation, a warning can be given by a Moderator or an Administrator.
When this happens, it has no use to discuss this warning as it has already been given. Official warnings are logged in the system.
For the second violation, depending on the severity of it, a second warning can be given.
Or, the Moderator or Administrator can decide to give a temporarily ban. Again the length of this ban depends on the severity.
When this user tries to evade the temp ban, by for example creating a clone account (see rule 1),
this immediately means that the temp ban will be converted to a permanent ban.
