It’s really annoying when someone backdoors you, especially near the start. But if they see you as a threat or an easy target, they are gonna throw you out, based on experience on Instagram games.
But there is a way to overcome it. Maybe when making alliances only choose people that you trust, and invite people to games that you fully trust, and that will get you far. do NOT be inactive the whole way through, you will go, and don't make yourself seem too much of a threat. I still to date do not follow this lol but give it a go! maybe it will work for you!
