What does it mean to have a blue dot next to someone's profile on KIK? Help? 3
I was kicked and people were automatically removed from my contacts and informed that I had been kicked. There's a blue light in front of his profile, I'm not sure what that means.
Do you tell everyone or is it just their kick account?
