I have an account that is banned from posting and sending mess. I don't know it's forever or not. After a period finding out, I know the reason why I'm banned. It's just the misunderstanding and language barrier. I posted the topic with the same name.
Thus, I write this post to apologize with the moderator and please unbanned my account.
I'm not an admin, nor a mod, but i've been on this forum for quite a while, so i've seen these issues far to many times... In 99,9% of the cases, answers to your questions are as follows:
1) if there is no timeframe indicated, it's a permanent ban. It basically means: "you, as a person, are banned from this forum forever"
2) it's against the rules to create a new account and continue posting while being banned. This is called ban evasion... Basically, when you're banned you're allowed to create 1 new account (or use 1 existing account) to open 1 topic in meta to discuss your ban. Since you created a new account and already created 2 posts in 2 topics:
https://bitcointalksearch.org/topic/m.45472151, this is called ban evasion (which is a bannable offence) (link to the archived topic:

Like i said: i've seen hundreds of people complaining about being banned, asking to pay off their ban, begging to be unbanned, even threatening with suicide... And for as long as i've been here, i've only seen 1 person actually being unbanned... Just to make sure you understand the odds of your appeal actually working.
I hope moderator can understand.
