When a post if flagged and then removed by the OP before a moderator sees it, the flag is declined due to the post being removed by the user. This affects the flag weight of the person who flagged the post even if the flag was accurate.
This isn't correct, the flag was deemed invalid by a moderator 3 hours before the post was deleted by the owner...the two events are unrelated.
If you hover over the "declined" or "deemed helpful" indicator on your flag weight screen, we show the time...you can compare this with the time the post was deleted to see they don't match up.
I'm pretty sure that it doesn't work the way you describe it. If a post is deleted, the flags on it are no longer visible, and in all cases I have seen until now the flag is automatically declared valid. I'm not completely sure if that also happens for self-deleted posts, I tried it and it worked, but I am a moderator so it might work differently then.
If your flag was deemed invalid, I would assume that a moderator manually invalidated your flag, and that the post was only self-deleted afterwards. I'm pretty sure that there is no auto-invalidation for flags.
the flag is declined due to the post being removed by the user
No, that's not true.
The flag still remains on the post and will be visible to Moderators via the flag queue. The Moderator can then decide whether it was helpful or not
I just tried this, the flag gets removed from the queue, but the flag gets marked as helpful in both cases
- When the OP flagged the post and the post was deleted by the OP
- When someone else flagged the post and the post was deleted by the OP
