If you'd rather not have any contact with someone on InterChat, you can block them.
- Open their profile.
- Tap ⋯ → Block.
Blocking works both ways: once you've blocked someone, neither of you can message, call or see each other's profile, stories or activity.
Blocking doesn't notify the other person. If you also want to report what they did, you can do that from the same place — see Reporting and what happens next.
You can unblock someone later if you change your mind, from their profile.
