Social media sites can be used as a powerful marketing platform. Sometimes especially newbie bloggers and website owners promote their content irresponsibly and the automated system of social networking websites blocks them from posting the content.
Same is with Facebook, when you post a number of links frequently on by one then it blocks your account and sometimes the website but usually these types of blocks are temporary and you get automatically unblocked after a few minutes, hours or week….But sometimes when it blocks your website permanently, in such type of case if you think it was done by some error and the content you were posting was not abusive and it was according to Facebook TOC then you may fill up the Facebook’s Blocked from Adding Content Form and wait ;-)
