If you can demonstrate it was just a lazy error with no financial gain and you were helping by providing information for someone there is a chance.
As far as I know,the rules have not changed,and whether it's laziness,for no financial gain,being drunk, or providing information etc, as long as its plagiarism/copy/pasting it's a straight up ban and it's permanent and nothing can be done about it
It's best if you quit raising the OP's hopes, at least until theymos changes something about banned accounts which I doubt he'll do anytime soon
If you're providing information that's not yours for others to learn,you can also indicate to others who's the original author of the info
