I do strongly believe it depends on the severity of the thing they did. For example, if someone goes on a massive RDM spree in GZ in Kavala they surely only gets a last change, if any chance at all. If someone just slightly breaks RP for example saying "on this server" in some sort of context, im sure they just get unbanned as long as they show the admins that they have understood what they did. Hope this answered your question.
