I flagged a question for mod attention as it look a better fit Android Enthusiasts. The question was since put on hold but my flag remains active. I would have expected it to have either been disputed or declined as one of the users was voted to put on hold was 10K+ but perhaps it works differently as my flag was for mod attention?
So I assume this flag might be sitting there a while and this has got me wondering. Do flags have a built in timeout, especially normal migrate flags or do they just sit in the queue forever until actioned one way or another?
You had flagged that question with a custom "Other" flag, so the flag couldn't be automatically cleared when the question was closed (since your flag could have been literally anything, there's no way to automatically tell if it was valid or not).
There is currently a bit of a flag backlog on "Other" flags on Stack Overflow, but we are working on it. These flags won't just time out. We'll have to look at each one.
