It won’t alert us. It might get our attention. Pinging us notifies us. People have helped a lot with that lately.  Downvoting makes the post go down and the upvotes stay at the top and be more visible. I’m talking about downvoting submission posts. We do delete them depending on what it is. If it’s lame and has no link, no value, poor quality, etc.. then we do remove it.  We’ve gone thru trial and error. You would not believe the swarm of attacks would hit us if we started removing stupid comments. What may be stupid to me, may not be to someone else. People have that right. We have much more peace when we just downvote.
