Someone is messaging me and I can't reply

That person has been identified as a serial killer.

I'm guessing they either blocked you or set their messaging settings to exclude users outside of certain parameters.

You need to set your age higher to 18 or over. It's a weird bit of segregation they have going on.

Lol weird. Sounds like you were blocked either personally or by settings.

I think it means they've got their settings so only certain aged people can talk to them. If their hassling you report them to SW. But keep the messages so they can sort it. If you can't message them back don't worry your head over it 😊

Most likely an age thing

It means your setting or theirs on their profile wont allow you to view it. Sometimes it means they have blocked you lol. Yours tells me I'm not allowed to view your profile

That the one that sent you the msg´s blocked you after doing it.
Or that same one is, with another user name but same IP, someone you´ve previously blocked.

:o

Someone has messaged you and then blocked you.
