Wrong. Most internet forums are privately owned, and thus the concept doesn't apply. Plus, trolling and harassment isn't free speech. Conflating the two is insulting to those who are fighting for actual free speech, in places where they will be arrested for advocating that.
I have a hard time knowing who is a troll as there are times when people become one but not in their normal behavior. I remember recently there was a study on that listed here which was interesting. Also, your negative tone for example could be interpreted as trolling if you put lots of those types of responses, not saying you are of course, but some AI might give you a false positive on extreme opinions.
What I meant was not the person trolling but the person viewing content, just being able to have their own filter, where the filter is not controlled by some 3rd party but under your own so let's say the 3rd party couldn't suddenly remove the option. More about control than privacy in that case.
