Seems like quite a few topics have been necro-ed but in a way, it is better to continue an existing thread than creating a new one especially if the topic is relevant. It does help to review the history of how things may have changed or not.
To be fair, i have only been met with polite replies to the point of being courteous by many of the senior forum members and players whose SR are higher than mine (which would be almost everyone because i am playing in Bronze at the moment).
I had also made asked a similar question back in Aug 2018 and the replies are very telling:
So no, not necessarily.
However, i do applaud the fact that the Thread Starter, NotASmurf had been kind enough to point out that many other players had been less than cordial in their replies and tone to less skilled players.
