@XejiNord11 based on the reason in description i assume that he just need to contact moderator to get unbanned
Regarding Nulceus, i do not know the details. But in case if he was perma banned only for insult i believe he could try to contact to other moderators. Have he tried to do that? Anyway if he is the one who DDOS FAF i feel no compassion towards him no matter the reason he was banned.
And as many already stated, in most cases permaban should be applied only for cheaters. One year ban is already quite hard measure.
