Something happened in my area nearly 20 years ago.
People were getting DF'd every meeting for 6 weeks in a row.
It was really unerving. seems like 20ish people were involved.
about 50/50 DF to reproved.
I never really got to the bottom of the "wrongdoing".
I seem to remember gossip about satanism/witchcraft being whispered and quickly ignored...
Very few came back to "the truth".
I agree, people "in" want to be there for the most part. They will leave first, instead getting DF'd.
That's what I did.
