Hi guys! I’m a teacher and I share the board with two of my students, but one day I’ve noticed that some other people come to our board. They usually come every 2-3 mins, stay for 5 sec and then go. And then come again with different avatars. I’ve created a new board, gave the link to my students, but all these strangers also came to our new board. I have set a password on my board and only shared it with my students, and even after that some strangers still come to my board. How can it be possible?
