@blackgreen @HenryEcker For what it's worth, as a mod, I prefer
SIM. It doesn't do as much as Advanced Flagging does, but what it does do is more useful and appropriate for moderators. I never got into using Advanced Flagging as a non-mod, though, so I guess that's a large part of why I don't prefer it. With SIM, you can easily check whether a particular post has been reported (and, if so, get a link to the MS report), and you can also now report it right there from the page, with no risk of a flag automatically being raised that would nuke the post.
