Thats untrue - in that what you describe is the kind of trolling we would wish for because its benign.

Trolls actively target forums for support groups. Today they can attack groups and classes of people.

At this point, expecting people to "grow a thick skin" is not an option, because a major aspect of their life is fighting for their rights against people who are attacking them, or people who have hurt them.

At this juncture the troll loses all rights over the definition and interpretation of how their action should be perceived.

Instead most normal people just see it as vandalism and stop caring about whether it was for the lulz or not.

And as stated in the article - NOT responding to a troll who is attacking someone makes you complicit.

Your definition of 'complicit' appears to be flawed.

Choosing not to be involved is clearly not the same as actually starting the behavior to begin with.

Being someone who choses to take offense and get upset about every little thing is their problem. Not everyone elses.

Generally speaking, you and I agree on that much.

However, we're talking about how filters and algorithms won't stop people from being dicks to each other.
