noDo you have any affiliate link or words like 'hack' in your URL/landing page?
its posts, the website is ok.Sometimes Facebook may block your URL for the multiple shares of the Facebook Groups or the Facebook may assume your URL as Spammy.
Wait for some days and post the URL again to get the solutions.
Thanks
Use pretty link to create a bunch of links and redirect them all to your desired page.
yes, and how i make a dealy between each group post?are you using massplanner?? if you are make sure all the posts arent being posted at the same time
Maybe the content from that link is not allowed by fb , even that PLAY button that is used by many on video picture is not allowed.
