Why can't I stop people from inviting me to group chats on kik? Someone has been harassing me on kik all week by continually adding me group chats that I did not ask to be part of. The person is blocked, but they are still able to add me to group chats against my will - I don't have the option of accepting or not, it just happens.

If I have to abandon the platform and find another way to talk with my friends overseas I will, but I'm hoping there's some way I can stop this. (And yes, I've reported the offending user to kik support, but they're terribly slow and now it's the weekend...)

I apologize in advance if this isn't a good community for this question, I just can't find an answer anywhere else I can't believe that there isn't one.
The answer is: you cannot. Either wait out the harassment, don't open the app for a while, or switch discussion platforms with the people you care to talk to. All unsatisfying solutions, but... they are the only ones.
