Anyone can flag a message they think is in breach of the community guidelines. If three people flag the same message, that message is automatically hidden.
Since the flagged post indicates how many people flagged it as inappropriate, off-topic or spam, the flaggee (so to speak) should have some indication of what it is about the post that cause people to take offense. If they then edit their post, it will automatically be unhidden, unless flagged again.
This is where self-reflection comes in. And if you get flagged a lot, then I’d say it’s more likely an issue with the way you present your posts, rather than an issue with the people who flag it.
That’s the automatic system. It helps the community keep itself in check when no moderator is available to step in.
In extreme cases where a lot of posts are getting a lot of flags, an entire topic may be automatically closed. This system keeps topics that have devolved into open war from going nuclear to preserve a healthy atmosphere.
On top of that, all moderators get a notification of every flag. That means we look at every flagged post, whether it’s received a single flag or ten. Sometimes it’s clear what needs to happen, sometimes we ask our colleagues to have a look for a second opinion.
Not every flagged post gets deleted. We may decide that the flag itself was an over-reaction, or downright inappropriate.
The system actually keeps track of all of that, so we will know if someone goes on a random flagging spree. And we will act on it – after all, every unnecessary flag is more unnecessary work for us, and we’re busy enough as it is.
We try to be fair in our judgement, always. That said, our job is not to be impartial. We are wholly on the side of Eve’s success. And though Eve’s success relies on people disagreeing with what we say and do (we will never delete a post just because you disagreed with us) it also relies on a healthy community (we may delete a post if we feel it serves no purpose other than to agitate).
And it’s a fact: moderators are humans too, and so we will definitely make mistakes.
But we try our best not to.
