avoid equal comments
Recently, I clicked on a comment button and it didn't respond. I clicked again and nothing, so I clicked one more time before realizing that it was just a lag. But three comments were posted.
Yeah, some websites look at your previous submissions, and if you posted a comment that's exactly the same just a few seconds ago then it detects your repost and doesn't post the comment. I think this would be a good thing to implement. Have you posted your idea to the feedback on the left side, vitor?
