Well, the decision is up to the mods. Just wait if the mod who nuked your account will respond here.
Sure, the mod have a power and the experience to decide case by case, but for me a soft ban with a explicit motivation is a more educating way to prevent it from happening again.
No, Icoperf is banned, but it is probably not his main account. As long as Icoperf is banned, he cannot post using his main account (if he has one) because doing so is ban evasion. Evading a ban also is going to decrease any chances of future leniency. There is very little reason why any 12 post newbie is going to care about being banned.
Why the account should be perma-ban if it has a little post ? The rule need to be the same for leggendary member and for newbie.
