[HELP]Link Posting Goes Straight Banned On Facebook

Did you cloak your link or maybe you posted adult link in non related pages? or maybe you using spam accounts to harvest token?

What I can suggest is redirect them from google plus pages with links or the other trick is

create a redirector from site.google.com to and redirect to your adult link

Make sure it will take 3-5 sec before your user redirected to your adult link cause facebook will scrape the whole process. so you must sure that the FB scraper bot will land on your redirector pages so you are safe ( this only works in site.google.com with redirector script)

Hope it helps
