are we allowed to promote our infinite flight channel, if yes in what category.
Directly promoting your channel is against the rules, I believe. However, posting a #screenshots-and-videos topic with an Infinite Flight movie type thing and linking your channel is perfectly okay. A lot of spotters in the #real-world-aviation:spotting category, including myself, link our Instagram and JetPhotos pages in our topics.
There’s also the thread that I run: IFC YouTube Accounts Database
Feel free to let me know what yours is :)
