That one got in somehow.
You should see some of the ones that don’t get in. Grant set the system so they must register and be approved, I reject around 20 a day and likely the other admins do the same.
I've been rejecting several each day, but I think you get the majority because you typically check it earlier than I do each morning.
If I can get some time, I'm going to look through the software modifications to see if there's a spam filter somewhere. There used to be one, but it was taken down. Hopefully we aren't the only ones seeing these and someone has created a new mod to take care of it.
