Probably not possible, but would be a useful feature for me personally. Maybe like within the last 30 days. Most of the inflammatory threads I've seen on WoW general are from January 2019 users, and many of them already have the banned icon before I've clicked on it. (I'd assume there's a much shorter leash for a newly registered user that shares an IP with another registered account). One downside would be a drop in reporting of threads that need to be reported. NBD if not possible or not desired, just disregard if not.
