As some mentioned in here, since some people have actually be banned by mistake, would be better to rectify the message explaining that unless you are innocent and wrongly banned, there is no point in appealing.
Actually, I'm also agreeing with the @Piggy because I know how I felt when I got auto-banned by one of the global mod by mistakenly.
In my case, I have created this
SMART CONTRACTS, simply explained... thread by transcribing the content of a video and I have already mentioned the link of the original video. But one member misunderstood my wording (actually it's my mistake not using the right word) in the OP and report my thread to one of the mod. Then mod auto banned me while I am writing my explanation to the member who claimed that I'm a plagiarist. Next day @theymos unbanned me with the request made by the global mod by reading my ban appeal.
I just want to express there can be some misunderstanding by even mods. Luckily I knew why I have been auto-banned since the member posted his claim in my thread. If he didn't do that I won't be able to find out the reason for my auto ban. Sometimes it would be the end up my career in bitcointalk forum since most of my friends told me there is little chance that you get unbanned and it will take a long time with the request system which isn't helpful as my observations. Therefore I also believed that
reason to be shown on their ban message with the reference post. If that happened I believed most of the copy-paste spammers would think it is useless to create a ban appeal thread in Meta unless they have strong evidence. Meta is now almost filled with only ban appeals and appeals of hacked accounts. Showing the reason for banning wouldn't do any harm at all but can reduce the some of the useless requests which already clogged the Meta.
Edit - The author of the medium article excerpted the content of the video without mentioning the source. I just shared the original source but not the plagiarist (medium author). That's what misunderstood the member who claimed that I'm a plagiarist.
