I already created a similar topic, and everything was discussed in sufficient detail there.
https://bitcointalk.org/index.php?topic=5388389.msg59430082#msg59430082A copy will always remain a copy. And this rule still works: moderators block accounts.
But this rule does not work when there is a paraphrase. This is the case for the last case, which is presented on the topic of plagiarism. Here, of course, there are questions. A person writes posts only to fill the quota set by his subscription company, and as we can see, he is completely far from sports. And just such a paraphrase looks very bright and noticeable. This user would probably be helped by the prohibition of signatures for any period so that he would accept and realize his mistakes.
Be that as it may, this topic has already been discussed, and we are powerless to change these rules. The moderators have their own views on this. However, I don't think it's best to ignore plagiarism altogether. Since this will bring the forum back to the side of spam and garbage, which is something everyone here seems to be fighting hard against.
