@alice_follows_rabbit You know, that's interesting. My account that was banned was actively used under Linux and Android only.
Then, I will get locked out, and they want me to go through the facial verification. It happened 3 times, IIRC, and the 4th time, they no longer approved my facial verification (even though I have the correct secret key they gave).
No reasons at all. It was like some agent got tired and permanently banned me. I was probably disturbing that #Instagram's agent's quota.
