Ladyrose and Pookie were not insulting or provoking iEminem in Dutch. As for provoking in English - iEminem, Pookie and LadyRose all try to instigate arguments.
In the replay, we see that iEminem was trying to fix his low fps issue and wanted help from other players, but a few moments later, LadyRose started targeting iEminem and Pookie interfered a while later.

I think removing iEminem's warning is fair at this point, as he is clearly being provoked by LadyRose and Pookie.
