I tend not to agree with the approach of just ignoring trolling or other inconveniences and pettiness we all find ourselves confronted with at various times during our lives.In "real life" I'm not bashful about shining a spotlight on inappropriate behavior and appreciate it when friends or even strangers make me aware of boorish behavior I've engaged in. This is how we grow as human beings.
This assumes that someone has the moral compass to look inward and make changes when appropriate. At the end of the day we all have our own values and I can't tell you what's "appropriate" anymore than you can tell me what's "appropriate".
It's a different game on the internet, and in my experience a waste of time to engage with trolls. Good luck though.
