Add option to rate adverts for better ad recommendations.
Advert for psycho-sexologist Audible book has become nothing but obnoxious to see/hear after it has frequently been played on every stream.
An option to rate adverts via mobile app would be ideal for better recommendations specific to genres chosen by every user; instead of the same adverts pushed by servers that are only based on country/region and often played too frequently and/or inappropriate for all viewers etc.
Better adverts will appease more users, if adverts are needed to be watched.
Voting is integrated into Twitch chat. When there are ads to be played, let the viewers decide which one(s) should play. This weeds out ads which the viewers of a channel don't like or have seen too often, and it will give Twitch useful feedback on the longevity and/or interest level of ads to take back to advertisers.
To avoid spamming the chat with polls, the results of an ad poll will apply to any ads played on the channel for at least two hours.
