Player sensitivity = Ban or Strike, even if you're just helping??

I was playing the new bot mode, level 100. It was already discussed pre-game that we need to clear waves for the strat because Zed didn't know how to play it..

Later in the game GP was bot and asked me to switch with him because he couldn't keep up with the lane. so I asked GP "do you know how to cascade your barrels?"

Kogmaw who was laning with him, apparently queued together, started telling me I was harassing him, telling him what to do, etc.

I explained it was nothing like that I was trying to give an alternative to switching lanes with him, perhaps he could try a different way of killing the waves.

Kog kept going even after the match.. all from one suggestion. Why are so many players so overly sensitive these days to a helpful suggestion? I truly was trying to teach him that he could cascade barrels to clear the waves easier and got interrupted by a very defensive kogmaw... Another player on my team told kog to chill and stop harassing me (i forget the exact words) This was the only thing I told him and kog just went off on me.... almost to the point it felt he was trolling me.

I feel like now I'll be banned (or a strike towards this) for harassment, reported by kogmaw when I did no such thing.
