If a user copies someone else's article or a post from the forum, then translates it into another language, and posts a new post in the locale into which the text was translated.
Is this considered plagiarism, with the condition that there are absolutely no links to sources? That is, we can assume that the person who wrote the post assumes the authorship.
Such as post should mark as obvious plagiarism. Adding source links would consider as translation, otherwise, it should consider plagiarism. I can't find any reasonable excuse why shouldn't it consider plagiarism. I don't know why your report still pending, perhaps it would easier to handle for local moderators. You can report to the moderator from the local board as well with the post link that you made reported on the LoyceV thread. So, local moderators would notice and take action against plagiariser.
