Friends & direct messages
Adding a friend
Tap a user’s profile → Add friend. They’ll get a request to accept.
Direct messages
Once you’re friends, start a DM from their profile or the Friends tab. DMs are 1:1 and persistent.
Friend requests setting
In Settings → Profile you can choose who can send you friend requests: anyone, friends-of-friends, or no one.
Blocking
If someone’s bothering you, block them from their profile. Blocked users can’t message or friend-request you.
