Thank you for your quick reply. I can block specific channels through the method you suggested when the channel is accessed through a web browser, that works fine and blocks the channel. But when someone knows the direct URL or keyword for a specific video in the channel, the filtering does not work (it is not practical to manually add all the video identifiers for channels which contain tens or hundreds of videos).
I seems to me the XG needs to query the youtube API for a listing of all the videos belonging to the channel and create a dynamic list containing the unique video IDs and block these. The challenge likely is that the XG needs to understand the youtube API so it can filter out the complete JSON/XML/etc. in the response of the API request, so that the video, descriptive text, etc. is filtered out and not shown in the list of videos displayed in the app. Is this something which can be done via application filtering or content filtering, or is this a feature request?
