Said that in the past few days, she said she was able to recover two of her pages.
How many did you lose?
Thanks. Over 20 the same day… 
So sorry to hear that. Facebook can be ruthless. Did you have them all under one account? If so, there is a good chance that’s how you were targeted.
Yes, we had several profiles Editing the pages… 
You had to had something in common between them. Pushing the same sites? This happened to me a few years ago, lost around 20 pages.
