Yep, whenever people text me an Instagram or TikTok URL, I just scroll past it. I don't even bother to find out what it's supposed to be about, it's completely inconsequential to me.
It's like they're trying to show you a party that's going on in some private location, but you don't get in, because you don't have an account. Well then, they say, if the account is free and you still don't make it, it's not our fault. So they close you out.
You telling them to "just copy and paste the content" is like telling them to send you a photo/video of the party. It's not the same as being there.
I have told my wife and several of my friends stop sending me things from ________, ________, and _________. I can't see them and I refuse to do what is required.
