Little inquiry, do plagiarized contents gets deleted by the mods when a user is banned, not nuked?
I used to think the post is allowed to stay up as it could act as prove later in case of an appeal (although LoyceV's archive covers this). The discussion could also still be relevant and something other members can learn from, even though it breaks forum rules.
That's actually a good question. I do think that some of the posts get deleted, but not all. I don't know whether it has anything to do with the amount of replies plagiarized opening post of topic got, but I just checked some of my previous reports and I can see that topic is still there (while having bunch of replies) despite poster being banned.
Then again, it could be that you are right and none of the plagiarized posts are deleted unless user is nuked but I could swear that some of them got deleted while user just get banned. Maybe mods can clear this up.
Usually, I do not reply if I notice the thread or post has plagiarized. Rather than just report and moderators take action against plagiariser.
My rule of thumb: if I see unusually well written post from a newbie user that looks like it could be a plagiarism, I just skip it (and check whether it's plagiarized). Maybe I am too paranoid, but that's how I deal with these things, I don't want to engage in conversation that starts in dishonest way.
