Bitcointalk is the only forum I frequently visit that even cares about plagiarism, and in many cases it's just very convenient to quickly show a certain text.
I may be wrong, but I am not aware that there is another forum that allows its users to make money just by participating in various discussions. As we could see in that big wave of banned users, a significant percentage of them just went down the line of the least resistance and instead of the original content engaged in plagiarism. If this rule was not so strict, I am sure that many would still pretend to be
smart members by presenting other people's achievements as their own.
I also reported to mods that last plagiarism case, hopefully that helps and he gets removed from this forum. At least until he comes back with a new account.
Since the user has publicly thanked for the warning and promised not to repeat the same mistake, and he still does - I don't think he understands what plagiarism is, there is no other explanation. It seems that I will also join those who will report his posts, because it is really not clear to me that there is still no penalty for and more than an obvious violation of the rules.
