Seems as if anyone can add anyone to a Facebook Group.
There is no “opt in.”
In this case someone added Mike Arrington and I to the “NABLA” group
on Facebook. I know I’m not a member of NAMBLA, and I’m going to guess
that Mike isn’t either.
I’ve now been assigned to a group that advocates… well…. ummm….
you can look it up–it’s very bad.
1. I was never asked to join the NABLA group
2. I was never informed that I was “force-joined” to the NABLA group.
