Well if they copy Twitch I suspect it will be circumvented very quickly. My adblock works just fine for Twitch, I do not see any adverts (unless I open using incognito).

I've enabled uBlock Origin in Incognito mode as well. Highly recommended unless you have a compelling reason not to.

Ublock isn't working for me on twitch.
