Looks like this may be
[status-completed]... see this answer by Jeff.
This used to be titled "Why can you only flag a given post for mod attention once?" I changed the title because I morphed the post into a feature request. The body of the question, on the other hand, already illustrated the rationale, so no change there.
According to this post, users can only flag a given post for moderator attention one time ("The moderator flag is a one time only flag."). What's the reason for that? It seems to me that the following could occur:
- User A flags post for mod attention
- Mod looks at post, maybe takes an action, clears post from mod queue
- User B edits post and introduces a new problem
- User A attempts to flag post again, but attempt fails
Why shouldn't user A be able to re-flag the post? Would the attempt to re-flag be met with an active error message or a silent failure? In the latter case, the user might not even know to use the backup "e-mail the staff" approach to notify a mod.
EDIT 1: According to @random♦:
Tested, even mods are only allowed one flag a post.
There isn't much opining going on, but it seems like all of it is pro-change. So, adding the feature-request tag.
