It’s not for you to say what people can or can’t post here. Some of us have many years of experience working with the Twitch API, and in some cases closed beta testing on these products, so we do have insight and experience of the potential implications your suggestion has had.
Maybe Twitch will take your feedback on board and find a way to better handle this, or maybe they wont. Either way it’s perfectly reasonable for people to voice reasons as to potential problems, and just because you don’t like other peoples insight on the matter if it goes against what you want to do with your own app regardless of what other peoples implementations are that doesn’t mean our posts are any less valid and worthwhile to anyone else reading this thread.
