Might seem daft but if you run a group on FB and get too many dings for breaking various word filters or 'community standards' which is easy to do...
For example, mistyping 'you dog' instead of 'your dog'...
Then you can get temporarily suspended, unable to post in groups or do admin tasks etc etc, or worse!
I run or admin around 30 groups, some of which are income generating. I cannot risk losing functionality on FB because I wrote 'your bitch is dead pretty' or 'I have died of cuteness overload you twat, stop sending me puppy porn'...
Even video sound content can be monitored, I have had friends have accounts suspended, videos removed, for totally innocent commentary, that is flagged because the bots do not grasp context at all.
FB is rolling out the ability for admins to say 'no FB, this is actually ok in the context of our group' but it is slow (not in any of the groups I currently manage!)
