My friend streams every time he plays, usually getting a couple of viewers. He offers support to his followers, helping with raids and other things. He enjoys what he does. Don't expect tons of followers at first. Just enjoy what you are doing, stream while casually playing starting off and you'll eventually build up some followers. I will not lie about this, but when you get a facecam, you'll get followers easier because twitch is a realm currently in drought with a lot of thirsty people. If you find that these people are harrassing you, you can always ban them. TL;DR Enjoy yourself and you'll build up.
