<…> we are newbie and we need some guide about how to avoid banning in bitcoin forum. But i can not find any info about this problem
It’s only a problem really if you don’t apply common sense to what you do on the forum. One shouldn’t even have to be concerned with being banned, unless he is going to cut corners. You see, the most frequent reasons for being banned are:
- Plagiarism: Copying and pasting somebody else’s post or article, be it fully or partially, without quoting and/or referencing the original author. If you introduce slight modifications that is still considered plagiarism.
- Very low quality posts: creating posts that are meaningless, and do not add anything of value (i.e. “too the moon” type of posts).
- Having Alt accounts that break the rules related to having multiple accounts (i.e. farming accounts to participate in the same campaign).
Those are the top reasons I’ve come across, but there are more. Take a look at the rules here:
Unofficial list of (official) Bitcointalk.org rules, guidelines, FAQ.
The duration of the ban is at the moderators discretion, ranging from a few days to permanent (plagiarism is permanent in almost every single case). If you are banned, it is you who is banned from the forum, so you are not allowed to use any Alt accounts nor create any more new accounts ever again (except to set you case in the Meta section).
