I've found that it's pretty easy to get people to inadvertently accept FaceTime calls if you continuously spam them. (I was on the receiving end of this attack.) Here's how it works.<p>1- It's very easy and instantaneous to redial someone on FaceTime if they decline your call. You can just spam the call button and the target will get a continuous ring, basically.<p>2- Even if they turn on Do Not Disturb, many people have "Repeated Calls" enabled, which lets repeat FaceTime calls break through Do Not Disturb. Neat!<p>3- Now they are frustrated and want to throw their phone in a bucket of water to shut it up. The only way to block you is now to get your "info" in the recent callers list, scroll down and hit the "Block this caller" option. However the constant stream of incoming FaceTime calls takes over the UI every couple seconds.<p>As they fiddle with their phone trying to navigate to your info and/or hit decline, eventually they inadvertently hit accept, and you see their face.
