This question already has an answer here:
On Stack Overflow, a new user forgot to add the language tag on this post. I asked him about it. After getting the reply, I edited the post to include language tag.
Then I forgot about it for three days and today I went to the post, deleted my own query comment and then moved on to flag the OP's reply as obsolete (since the tag was now added to the post and the brief comment saying "swift....." did not add any value to the post).
To my surprise, as soon as I hit the flag button, the comment was instantly removed and my flag was marked as helpful.
I have never seen obsolete flags getting reviewed so quickly (within 2 seconds, If I am being generous).
How did the comment got deleted so quickly? I can think of only two explanations off the top of my head:
- Obsolete flags retain a count like Spam flag. After hitting a total of six flags, the target comment gets automatically deleted.
- It was just a coincidence and a moderator just happened to be around to review it within seconds.
Since this is about flagging mechanism which is shared across the network, I thought it would be better to ask this question here instead of Meta Stack Overflow. Do let me know if it is better suited to MSO instead.
