You did not understand what I am saying. Binance.us got verified. If binance.us got verified, why won't their official Facebook account not got verified too?
Because all the social media under binance.com are under the control of the ones that are doing the check, just as the binance.us domain is, the social media links under binance.us are under that team's control, so there is a simple explanation, if those accounts are not getting verified you can also decline responsibility for anything that happens with them, which would be totally normal for somebody to do since they don't actually control them.
The real bug I see on that page is that things like
https://www.binance.charity are not recognized but binance.charity is.
