The Problem:
My daily flags are spent on a handful of people, who I see again the next time I log in with the same nasty behavior. They won't get banned, they actually have huge positive reputations by never answering with insults, only using them in the comment section instead.
The tags I am interested in are also the ones I post questions to, so there is no way to ever escape these people.
I mean, imagine if someone just comes along to your question and says your question doesn't have any links, or the code you provide doesn't work. That's a useful comment, right? Except when they're wrong.
So this is trolling. It's harmless though... Right?
Moderators and anyone with 3000 reputation may vote to close a question as a duplicate.
So how can you defend against 3000 reputation person voting towards a nonsensical removal?
Solution: Better/More moderation:
Moderation doesn't fix this: Even if moderators could have the resources, creating trash would still be easier and faster than cleaning it.
Moderators having to review every flagged comment or bogus removal request by hand isn't sustainable.
Solution: Vote on comments:
This could work, but it would also cause lot of bad side effects. Voting is currently a proof-of-stake: Best way to gain reputation is to have reputation.
You can't post questions if your last question was downvoted. If you want to troll people, you can downvote every user you see; this will prevent them from ever asking any questions. If they're new users, this prevents them from gaining any reputation, as they cannot ask new questions, effectively blocking them from the site for a while.
But wait, if new users can be blocked, why shouldn't they be able to block?
Solution: Mute/block users.
Consider the following: Muting. Nothing changes except your profile doesn't see the other profile's messages. This prevents nasty comments, but it still allows you to be trolled.
Blocking would be a more aggressive solution, where blocked users cannot interact with your answers or questions, which prevents trolling entirely.
Of course, you shouldn't be able to a block or mute moderators; that'd be stupid.
And why shouldn't there be blocking? If harassment and trolling is this widespread and reporting cannot fix it, there should be user-lever solutions. This is a social network: We have upvotes and upvote points, badges, activities, birthdays, profile pages and avatars. We are meant to interact with each other as unique humans. What is the point of all this flair if not to show off who you are? You are encouraged not to hide your individuality. Yet, everyone must like everyone else.
We shouldn't rely on moderators to distance ourselves from everyone we dislike; we should be able do it ourselves.
