Thanks for the links. Strangely I cannot get past the arhive.is "I am not a robot" wall. I click it, then it refreshes, I click it again, and then it asks me to find Traffic Lights, and then "I am not a robot," repeat.
I don't know what changed, but in recent months it has become impossible to pass. Not a single success, whereas earlier it wasn't failing ever. Firefox on Android. Maybe I look like a bot now, for whatever reason.
