To complain about a negative rating the poster needs to know what he wrote in the first place. In some cases, he may not even remember for a deleted post. So the problem remains. People can't go around complaining about things that they themselves are not sure about.
That is of course assuming that one gets a notification, which is generally not the case for deleted posts.
I think I have explained it well enough multiple times for anybody to understand the problem here. Rest is up to you and @

Thanks!
