I've learned that if you confirm a casting and it is deconfirmed enough times, you are permanently banned from confirming castings. This is a problem because some users could be butthurt about a confirmed casting not being their choice and deconfirm it. I hope this is fixed in the next site update as it is very inconvenient for when I'm working on my stories.
Barred for confirming castings
I got barred for confirming Marvel TV castings since apparently they're not "MCU confirmed", but then I got unbarred.
Do you know who unbarred you?
