This got me wondering, if multiple users report the same post will they all get credit for reporting the post?
No. Who ever got to report that post first will be the only one to receive the credit. The others will have the mark of "
Bad". Afaik
Or does the report stay as unhandled?
It will only remain
unhandled if Moderators didn't want to respond on it or they leave as it is. Afaik
My suggestion, if a post is reported then could the report to moderator option be removed from the reported post? This way multiple users are not reporting the same posts as well as moderators do not have to look at the same report over and over. Seems like it would be a better system.
Not possible, some reports might be getting piled up sometimes, so they might also forget looking on those reports.
