He told me the post that was claimed to have been erred has been deleted, isn't that enough punishment? Then the account got banned permanently, up to 4 accounts, there's no hope when one appeals, i am appealing to the moderator responsible to please unban my friends account @da_primate(https://bitcointalksearch.org/user/daprimate-947001).
He promised to abide by the rules of the forum to the letters going forward.
We don't see that it was on behalf of your friend. If it was so, shouldn't you be not a newbie here? I mean such reasoning could still point that you are that "friend" that were banned and just posted such thread for what purpose? Un-ban a shitposter that most of his post only is a one-liner and even had many of them on off-topic section? Dude this isn't a twitter thing that you could post as shorter as you want. Yes he had freedom, but making 4 accounts with the same points of unnecessary short posts would be enough reason to be banned. Also, with your newbie account "protecting" your friend is also a mere point that he is evading his ban.
Not to hate, but there's no unfair treatment for over the years until you voice out the impossible.
