You may encounter the following problems when registering your website on Facebook or Instagram.
The message is that “We restrict certain content and actions to protect our community. Tell us if you think we made mistake.”
I tried all sorts of ways to solve this problem, but I could not find a solution. I contacted Facebook and Instagram, but I did not get the answer I wanted. After a number of efforts, I finally solved this problem.
The cause of the problem was server IP. Server IP was blacklisted. So, if you face this problem, please contact your web hosting service provider and ask them to change the server IP.
Good luck.
