No, there is nothing you have to do now. In Primal anyone (who wants to) can follow your mute list. The only thing you can do, is to keep it so narrow that people don't feel they miss out, when following it.
For example I looked at Roya's mute list and has too many accounts I wouldn't want to mute.

Ahhh okay. If I don’t like people’s stuff I just unfollow them. If they’re hateful or extreme, then I mute them.
Why would you blindly follow anyone elses block list?
That shit broke Mastodon lol
