What happens when a user flags content (question or answer or a comment) on Stack Overflow? Is the flagged content sent to moderators? How does Stack Overflow make sure that flagged content is, in fact, really inappropriate content, and not a malicious flagging good/relevant content?
- Spam and offensive flags go to moderators (and six of them will automatically delete the post)
- Vote to close flags (duplicate and "should be closed for another reason") go to the close vote queue (which is available to 3k+ users)
- Very Low Quality and Not An Answer go to both the mod queue and 10k queue
- "Other" flags go to moderators only
How does Stack Overflow make sure that flagged content is, in fact, really inappropriate content, and not a malicious flagging good/relevant content?
Excessive bad flagging i.e. big number of rejected flags will lead to revoking the ability to flag. Once upon a time there was something called flag weight that was affected by every single flag and determined how many flags you had and what's your priority in the queue. However that was replaced not long ago.
In short, in the new system if one cast at least 10 flags in a week and 25% of them are declined, he's being blocked from flagging (after getting a warning) for one to seven days.
