Yes, you can be banned if it's proven that you have plagiarized.
Nope, you won't get banned on bitcointalk for image plagiarism even if its proven that you took image from someone else and presented it as your own.
For example of something like that, take a look at
this case from few years ago when I exposed someone who took someone else's image and explicitly presented it as his own in order to fish some merit. Even though it was proved that it wasn't his image (I contacetd the original creator who confirmed me that) and he even admitted plagiarism, mods did nothing and all he got were few tags.
Nope, I’m afraid this isn’t sufficient evidence. Since this incident occurred outside of Bitcointalk, it’s challenging to confirm the identity of the person on the other end. Furthermore, the image was not initially posted on Bitcointalk.
What I’m trying to convey is that if the original image originated from Bitcointalk and someone shared that image here on Burocintalk, and then another individual copied and reposted it on Bitcointalk, that would indeed constitute clear-cut plagiarism.
I don’t understand why moderators won’t consider it plagiarism?
