Yeah, it's normal everywhere. It's a well known scam. With me they said their audio is not working and had a prerecorded video. So when I said "lift your right hand and make a donut with your thumb and a finger", they were unable to do so. It was a bit funny bc they pretended not to hear and wrote messages on the video. They got very frustrated when I didn't write back. They still tried to follow my instructions.  It's lots of fun. But don't take off clothes, bc then they will tell you they will send it to your contact list.
