Will a person be rewarded for creating a religious channel on YouTube to spread scholars' fatwas, sermons, and reminders of Allah, voiced by students of knowledge?

What you have mentioned is a good thing and a door among the doors of calling to Allah Almighty. We pray for you and for those who strive to disseminate knowledge through modern communication means, that you may be counted among the callers to Allah and attain the reward of spreading knowledge and guiding to good, for the Prophet, peace and blessings be upon him, said: "Indeed, among the good deeds and merits that will reach a believer after his death are: knowledge he taught and spread..." the Hadith.
