@BarryCarlyon In general I’d agree, but having the ability to gate with a user oauth token would provide legitimate services an avenue to get your online state. It would probably be pretty low on the priority queue if it was picked up at all, but I can see legitimate (and illegitimate) uses for the feature.
@Whois - Generally, defining ‘online’ is difficult. Usually the best you’re going to get is ‘did some action within the last time period’, which in terms of twitch, people lurk on chat all the time, leave video streams open, etc. None of it actually indicates the user is there, other than their computer exists in some fashion in the intarwebs.
