Is following a players orders a reportable offense?

So please do keep in mind this was aram A player i was playing with in aram told me and I quote to "go die and do damage" So of course as they are obviously the better player I should follow there commands. So i did and since i was playing karthus i ran to go die and then I ulted. Doing exactly what i was told to do. Wierdly the player that gave me the command and some others said I was trolling. How could I be? I followed their commands to a T so why was I the one getting witchhunted? Im just very confused by this as they had previously stated that I was a lower rank then them so I assumed I should follow there commands.

And to top it all off they were the ones who started this at first saying "useless" when i died to a burst which i took as a joke so i said it when it happened again. Then they started to type things like "do something" ( I cant remember exactly) but they were the provokers in this case so im still confused on how i am the troller.
