Post the user name and we can tell you.  No sense hiding it if he is permabanned.  

Spamming posts are non-sense, one-line, one-word, and non-constructive threads. Something like "Great!", "Yes", "+1", "reserved", "joined", etc.
In addition, spamming posts are repeated posts with same words at different topics in the forum. As time goes on, you will see by chance lots of cheaters in the forum publish same threads over and over again in order to spread information about scam project, scam exchanges, etc.
More seriously, copy & paste without quote will put posters under high risks of permanent bans due to plagiarism.
Furthermore, we also have spamming topics (not only spamming posts), lol.

hello sir, my friend was banned by moderator. his user name "rakib97" sir is this account come back possible..or have any way to appeal to recover this id..? if have any idea to you please get some suggestion regarding this issue...

Maybe he is plagiarizing his/her post which is something that you must not do, because you are stealing away the idea from other people which is not yours, to begin with. For me that is what I observed those who got permanently banned because the post he/she constructed is likely copy from the internet.

My posts are also like that, they are social media bounty reports. Are they not allowed?
My original account aroweyen was banned.

There are hundreds of similar accounts and thousands of similar posts.
The forum is being used as a free messenger service for these mindless social media campaigns, facilitating low quality spam with no benefit to BCT or the current efforts to improve overall post quality whatsoever.

As long as I don't see a link on the account which is banned, the filing that this is just alt account become stronger and stronger.

To add to this conversation, there are a lot of medium posts (I would call them medium just because there are a lot of shity posts like "Great" "I agree" and so on) which is never brings anything new to the discussion (just general shit about BTC vs ETH). This "medium" quality posts is alowed and they can be done without the deep knowledge of the crypto subject, and with the justified amount of time. I just don't get, why this bounty-spammers can't do this shit in the right way.

I think he is trying to say that you have been banned temporarily for 14 days because of spam posts and you will have that account back after that time period but you created another new account for asking about that quaery so you just have to only do posts in the meta section with your new account if your account was banned if you posts in the other sections at the ban time it will leads to permaban.

Posting reports about the social media bounties will not leads to ban but most of the managers are using submit fors for submitting your reposts but still many users posting reports on posts so it will be called as spam posts that's why you are banned temporarily.

If you want to know about the rules more read the rules again which will be stick onto the bounties section.

There is no relation betweeen the ban and negative trust.

Your accound will be given negative trust by the DT members if you are involving in the shady acctivities so they will mark you with the negative trust which means unworthy person to trust.But you still can make psot with the negative trusted accounts.

But ban means you will be no longer able to make post or send personal message to anyone until the ban time if in case it is permaban you will be no longer allowed here.
