When I looked at this subreddit yesterday two of the top posts were:

One, this one, implying that a "Latino" man was trying to kidnap OP, though now that they've commented more it sounds like it was probably just a guy looking for parking

and

Two, a guy claiming that armed robberies are "exploding" in DC right now and saying that we all know the races of the perpetrators, implying that obviously the problem is black people - and when I looked at his post history he was a BMW obsessed bro living in the Wharf area and he actually said that he thinks the National Guard should occupy DC "24/7" to crack down on crime. The guy was unhinged.

It's not an easy job (and also a job that they don't get paid for), but the moderators will have to keep an eye out for crime-panic posts that don't really have merit.
