I may not explained correctly. I meant multiple reports from one user. When same person report a post for second time, a warning would be helpful if the post is still in the same board.
It still doesn't matter that much as how many times do you report the same post? (though it does happen from time-to-time but it's not a big deal), though maybe it could be changed so once you click the report button it changes to
you have reported this post or you're blocked from reporting it again or something.
