I have sometimes got rattled and been a little sarcastic, but not abusive. But I have to agree with the previous comment regarding possible hacks, or the game being rigged.
I, also, play a bit live. For my white to go down is a rare thing. Here it goes down without mercy. In my case about 1 in five hits. I play very softly, so it is not a matter of blasting the balls out of sight.
I did once, find a way to make a screen shot and I did see that, on that one occasion, the rebound of the white gave no resemblance to the normal laws of geometry!
But, I suspect, on the other side of the coin, that there are quite a percentage of extremely good players who have, for carious egoistic reasons, got themselves to the bottom again. To play these guys, at my low level of skill, has no enjoyment whatsoever.
