 ### How do I know if the stream is eligible?
 
-Make sure you can find the origin of the broadcast using your favourite search engine or by following the domain of broadcast. If you used to see the channel under paywalls or subscription offers, it may likely be a copyright infringement. If you see a service with a probe period and available plans or you have found a link having unreadable parts of it in someone else's playlist, it's likely to expire soon. We typically look for pages with publicly accessible video players, as these are more likely to host broadcasts intended for public viewing. However, even in such cases, the underlying stream URLs are often protected and may only be accessible within your authenticated session. Examples of valid streams are shown below.
