Someone has been messaging me.

Hello all. I wonder if any of you have had a similar experience ?

Someone, with whom I have been chatting on and off for some time has messaged me in the last few days.

I saw no reply window and when I tried to see her profile, to do some checking there was a message like,
"You are not allowed to see this profile".

Has anyone else had this experience of, apparently, one way blocking ?

Is there anything I can do about it ?

Peter
