This is an open letter to Mr. Zuckerberg about his practices of blocking and banning animal rescuers/ crossposters who save, rescue, educate the public. However, sites with porn and animal violence have not been touched. Plus, FB has been banning private messages, friending, and deleteing messages and comments of people who are acitively involved in animal rescue. WHY??? Apparently a spam filter is to blame, but somehow, I think there is more to this story than that....we save living beings.....we are not spam.
