Well said. :)
The only problem I have with Twitter's policy is that is seems to be unevenly enforced. I get that it's their sandbox and I have to play by their rules to dig and make mud pies, but it's quite another when the "engaging in targeted harassment" flag is overused by sensitive people who believe words are more than just, well, words.
If they want to cut out the trolling, they are welcome to police their sandbox. I just wish it applied equally. Personally, the mute button is the coolest thing ever conceived by Twitter (I know, low bar). The reason it's so damn cool is the other user doesn't know they're muted. :) So they can yell like idiots 140 characters at a time and be none the wiser that their speech is not hitting my TL. :)
I don't put too much stock into the "harmful" nature of words. Speech has no agency. It is not something to be considered "weaponized." We can all agree that most of what passes for "harassment" on Twitter is people offended by dissent, or offended/angered that an assertion needs to be defended if one makes it.
There are some creepy things on Twitter. Thankfully block/mute work for most of them. And if a twitter user doesn't want to be sucked into the troll's world, that user should consider the source of the tweet before engaging.
Saves a LOT of time and headache, IMNSHO.
