facebook-groups
I'm the creator of a public Facebook group of my university. I added another administrator to help me to control the posts. Some time ago a member said that a post of his was deleted from the group. I didn't delete anything but maybe the other admin did, or the member deleted his own post. Now many people accuse me of deleting that post.
Is there any way to uncover who deleted the post?
Or is there any way to evidence that the other admin and I did not delete the post?
You are currently permitted to post up to 63,206 characters on Facebook in a status group or wall post. There is no difference.
In September, we increased the character limit on status updates to 5,000 characters. Today, we're announcing that you can now write posts with more than 60,000 characters. (1)

I set the exact limit to something nerdy. Facebook … Face Boo K … hex(FACE) - K … 64206 - 1000 = 63206 (2)

Instructions from Facebook on how to send messages to entire group.
How do I send a message to everyone in my group?
Any group member or admin can make posts in a group using the options at the top of the group. When a post is made, members are notified on Facebook and by email, and they can respond with comments. Members can change their notification settings, but they will always see new posts when they visit the group.
Group admins can’t send private messages to all members of a group. The best way to reach all members at once and start a discussion is to make a post in the group.

This is going to require a little coding and some Facebook Open Graph knowledge.
You must be logged into facebook :)
First you will need to query all the members of your group. Here is an example query
api.facebook.com/method/fql.query?query=select+gid%2C+uid+from+group_member+where+gid+%3D+146797922030397+limit+50&access_token=AAAAAAITEghMBAJDmxL89UqxXbZAqR4PwcIIE8nj74hiPi618zMJLuzJh1otaVC2XIxjmA78yzsxZC9pDcBZBaAW4He2ZCh1sVsYAbahvXwZDZD&format=json
This only works on groups you are a member of. Also my example link is set to take the first 50. If you need more adjust the Url query accordingly. The important number in this is the gid. Your gid can be found in the url of the group page.
Now you have all the uid (user ids)
These uid's can be used to get their user account names Example:
Here is Brad's
graph.facebook.com/220439
Take the account names and append @facebook.com
Create a csv with all the email addresses copy this line into Facebook messenger.
You would want to automate this in a script, as manually looking up each individual user name would be tedious.

If you tap 'more' (this has 3 dots above it) & then tap 'View Group info' & then tap 'Admin activity', a list of all activity including deletions & approvals should show up.
