I have previously made mistakes quoting posts, but it is usually when trying to trim down 4 or 5 embedded quotes, not when quoting a single post as in this case. Additionally, it is in general obviously meant to be a quote because I am then writing something in direct reply to the quote.
I agree with everything you've said, particularly about not punishing honest mistakes, but there are two things that are working against him here:
1 - There is no unclosed quote tag, or even bits of a tag, so after hitting "quote" he would have to have precisely deleted the before and after tags
2 - He added nothing of this own to the post, which you generally do after quoting someone
Edit:
Actually, looking at his post again, he's quoted someone else correctly first, before the alleged plagiarism underneath. Therefore, he can't possibly have misquoted the second post. It must have been a copy-paste job.
If I remember correctly, then I was trying to copy paste lines in that post and answer that in a few quotes in different Chrome tabs since quoting each sentence in the same tab of the mobile display is a nightmare.
Long story short, I ended up posting the copy-pasting the initial content of the main post and didn't bother to look into it and closed the tab in which i wrote my content (I can't look it in any other way).
Its hard to believe his story, especially when he said that he misquoted and made a post, but you don't make a same mistake twice or perhaps more on the same day.
Making the same mistake twice or thrice a day is suspicious indeed.
Take the example of my case.
I posted *by mistake as I've said above and didn't bother to look into it.
After that, I made a similar but not same mistake but with "[/quote]" [https://bitcointalk.org/index.php?topic=4870957.msg44203572#msg44203572]
I'll consider that a brain dead day for making that mistake.
Cases should be taken on a case by case basis, but there should be few exceptions. I suspect this user just used that as a desperate excuse to try get out of the ban, but is this just a one off?
Maybe or Maybe not I'll leave you to judge that.
Usually copy and pasters don't just do the one and have copied multiple posts and make a habit of it.
You can go through my post history and can manually check all the posts, If I'm found copy pasting another one then I'll leave the forum for good and stick with my IRL work.
So if you make mistakes but your intentions weren't to profit off of other people's hard work, the possibility of getting your account unbanned isn't completely out of the question.
Well, I was trying to profit off of the posts I made (
Wouldn't lie on that), but by adding my content into it after quoting it, Which ended up very bad for me for the mistake I committed in this case for the first time.
