How can you block people streaming on twitch?

I always look through the random list and would like to block it

With Better TTV you can hide the list of recommended streamers and set many other things. BTTV is an extension for your browser, so you can download it from your browser's settings.

Yes but I want to go through the list so only block the very weird people ^^

Oh, that is only possible with an extension for the browser. Some are presented here, choose one: https://www.reddit.com/..._streamer/
