A Facebook Closed Group moderator "...approved my request to join the group Au pairs & Host families Lleida (Catalonia-Spain)".
So I was able post and comment in that group.
Basically speaking, that Group was for Lleida locals interested to host budget tourists families.
I just briefly introduced myself as possible descendant of Sephardic Jews expelled from Spain (including Lleida, Catalonia) in 1492.

I found out that the Group was deleted on Facebook and recreated with a different name. And it looked that I was not welcome there anymore. :-)
