Nice investigative skills. Gotta say, though, isn't this something that should be mentioned to him privatively? However, I'm not complaining, this is amazing.
A lot of people flagged issues with them now and in the past, so it's good to show them that we, or more accurately Hiku in this case, are taking it seriously and on top of things. Also, PMing wouldn't work cause they couldn't read it. One of the main reasons not to do such things in thread is that people generally don't like getting called out publicly and it leads to tension in the future, but if it's gonna be a perm anyway, that's really not an issue. They also can't respond back, so the risk of serious derailing is minimal.
