This was just an idea, since they post news, and we have Press board, it would be more appropriate to have it there, of course, if there is reason to consider it something worth reading.
Oh sure, perhaps I misunderstood your previous post. Threads regarding substantial news stories which are actually newsworthy, and not just sites advertising themselves, could definitely be moved to Press, but don't just use it as a dumping ground for low quality spam.
The best chance to remove them is if we catch some post without source link, or wrong posted link - which can then be reported as plagiarism.
An imperfect solution, as that's not really what the plagiarism rule is designed for. Simply forgetting to add a link or a quote is not plagiarism, as you are not trying to pass the text of as your own. This is even more the case when an account has a long history of copying and pasting news articles, and no one could reasonably claim that this account is claiming that work as their own. Further, if they don't make a mistake, then they will continue indefinitely.
A better solution would be to start handing out escalating temporary bans for this kind of behavior.
