The Akisment spam filter is acting up and holding up a lot of comments it shouldn’t be blocking. If your comment doesn’t appear right away where in the past it had then it’s the spam filter. Every single one of my comments are being held up in it. So are about a dozen other members’ here.
Don’t ask why because I don’t know why…
It hiccups like this occasionally and goes away soon. I suspect it gets noticed and fixed at Akismet during normal working hours so it’s more prone to become a bothersome issue on weekends.
