Sorry, but if it wouldn't have been banned then there would be 1000x legitimately looking fake BOT accounts impersonating every politician in Europe, which IMHO is a lot worse considering the disinformation campaigns of trolls and foreign adversaries, so of course Meta would err on the side of caution here and assume every account of a politician is 99,9999% gonna be a bot and just ban it instantly.
The only correct solution is META having human support staff on call for such situations which i thought they did in Dublin, at least last time I checked ~8 or so years ago.
