I'm generally happy to tolerate ads to support the stream and platform, but sometimes ads come up that I never want to see again. Other advertising platforms provide a way for users to indicate that they do not like a particular ad, which prevents it from coming back up. I think this would provide value to advertisers, since it avoids repeatedly showing ads to unreceptive users; streamer s, since undesirable ads are less likely to drive users away from streams; and viewers who will on average see fewer irritating advertisements.
