I reviewed my previous post. It does have similarities with the post pointed out by icopress.
The DSA content I posted was not copied directly from the link he pointed out.
I'm still confused by this part: if it's a verbatim copy, it's copied. It doesn't matter if you use copy/paste or type it yourself.
Unless of course you own
https://www.programmersought.com/article/7824960278/, which also uses Chinese text in a screenshot, just like your post here.
I do not quite understand the purpose of posting handwritten calculations, since looking at these fuzzy images, it is impossible to distinguish anything.
At least it proves he spent effort on the post. That's what makes kxwhalexk stand out from the lazy (or even automated) copy/pasting to reach signature targets (which made me start this thread 4 years ago).
I barely see those cases anymore, so I'd say Bitcointalk is better now. But as "
Is Bitcointalk.org losing user base?" shows, we need users too

And I think we should be careful not to ban users for mistakes. I can't emphasize enough how unique Bitcointalk is on banning users for plagiarism. And although that makes perfect sense when it's a lazy way to earn from a signature campaign, I believe (some) users deserve a heads up first.
