I have a youtube channel just so I can comment on videos when I want. I have posted no videos or anything else. Yet I was notified that someone subscribed to my channel. Why would they do that?
It’s likely to be someone who hopes you’ll follow back or someone running some sort of scheme with shady links to shady stuff. Could be a bot. Or a secret admirer. Maybe they just want to keep their eyes on you.
