I'd you have to create a threads account, which shares and logins to your Instagram account, for it to be active, but people are being sent advice to follow accounts which haven't been activated, then this is bad faith behaviour and not misinformation.
not really. If the account never activates on Threads then nothing happens. It’s just a convenience. If they don’t offer this feature then you have to consistently keep checking to see when your friends activate their account and go find them. It’s objectively a worse experience to do it that way
