I thought they did say they knew.
But it is pretty standard to let kids announce their commitments themselves. Ironically one of the people who “amplified” their error here has repeatedly been called out for leaking commitments before kids make them.
I kinda agree with Vak, I thought what they said was fine. They did take responsibility, but called out the truth that not many people would have known if others didn’t amplify the error. By talking about it on FRL they made even more people aware of their mistake that probably hadn’t even seen it, I wouldn’t have been surprised if they didn’t address it at all. Flo probably should have deleted their own social media posts about it though.
