If someone is making a real life threat, then yes, it should be reported. But as I said, I can’t confirm on who is flagging who. Trust me, I get a ton of post still flagged, but I tend to just ignore them and let moderation deal with the post. If people here are flagging your post in this thread, then don’t try and worry about it. If moderation doesn’t find anything wrong with it, they’ll just restore it or ignore the flag and let it stay flagged.
And I know the feeling when someone makes a real-life threat and it feels like they get away with it, as this thread will tell you.
