I'm red tagging plagiarists from this point forward.
You shouldn't do that:
The system is for handling trade risk, not for flagging people for good/bad posts/personalities/ideas.
Mods won't do that, but you can wipe the post by yourself as long as you're not banned.
So what's happening is RainbowKun did some text spinning before posting and he seems to have combined multiple sources rather than plagiarizing an entire article.
When he posted dates and events in his (long) posts, I tried to find plagiarism (but couldn't find it). Based on his long detailed stories, it makes sense he used different references.
