Does system also handle few flags?

Question

My two recent flags were declined but I think they were valid ones.

• A Q was duplicate of 2 questions and in such cases we flag it to mod but after I flagged the Q, OP deleted it and my flag got declined:

  May 24 at 6:30 declined - Question is deleted now by OP

• A Q was spam but OP deleted the Q after I flagged it and my flag got declined:

  yesterday declined - deleted by post author

Now, when I try to flag something, the system gives warning:

Your recent flag was declined - please review it before flagging this post!

My questions are

• Were these flags handled by System or Mods?
• If mods then, weren't my flags supposed to be marked as helpful instead of declined?

Answer 1

• Were these flags handled by System or Mods?

Most of the flags are handled by moderators. However there are some exceptions like:

1. if the post is automatically flagged for low quality and gets edited, system validates the flag;
2. if the post gets 6 red flags (or a moderator's red flag) they are all automatically marked helpful,
3. if a comment flag gets too old, it is automatically disputed

etc.

• If mods then, weren't my flags supposed to be marked as helpful instead of declined?

Here was no further action to be taken, so I declined them. But yeah I agree these flags should have been marked helpful. It was a mistake from my side.
