Sekai Camera’s follow function and Twitter’s follow function can not be connected regardless of connection settings in Twitter.

We do not provide a setting to block ALL users from following you.
You will have to check the reply list and block individually.

On Sekai Life, display the profile of a user you want to remove/block, and tap “Block”.
Once this person is blocked, he/she will not be able to follow you until you unblock him/her.

You can check if others are following you through your profile on Sekai Life.
The number shown next to “Followers” are the number of users who are following you.
Tap on the number to see the list of users who are following you.
If you have 0 followers, you will not be able to tap.

There are two ways to follow other users. On Liveview (LANDSCAPE position), open the user’s profile from an AirTag of choice, and tap “Follow”. On Sekai Life (PORTRAIT position), tap “Follow” on the Sekai Life profile.
