Per Civil, no need to thank people for being considerate. They cannot vote "not civil" just because they disagree and then get your post removed if I have read the following correctly. (unlike what could happen with Disqus and each media's moderators?!)  

 Civil also has moderators after the three comment inspection anyway.  I think that is when the This comment has been removed part shows up. Not from posters reviews.
