Tagging a friend, or someone who gives you permission is fine. I even do it in my contest. But what isn't good is as you said, tagging for exposure. It could end badly if the wrong person has had a really bad day.

A little more advice: Be sure never to copy and paste material found online, and always source your images :) I know this was a vlog, but that will be especially valuable information should you choose to blog. Again, welcome to Hive, you are going to love it here once you learn your way around 🙌🙌🙌
