How to fix comments being automatically deleted on Facebook group post?
Why is my comment automatically deleted on Facebook?
~ It might be because you never update anything on your timeline but very active on other FB groups and pages and share lots of external links on the comment. If that's so, FB will detect your account as a fake or Spammer and block you from commenting on some particular post or group temporarily.
I will show you how to fix this.....
Log in to your facebook account...
Click the question button...Click "Report a problem" at the bottom
Now click "Something Isn't Working" from the popup
Select a product...If it is a group ...select group.
Now explain the problem....you can also attach screenshot....
Click send...
It might take some time but it really works.....Have a blessed day! ;-)
