Social Media Marketing

I've tried like ten thousand different website unblockers that get to Facebook. But when I get there all the little blue buttons won't do anything ( like "post" "share" "accept" "ignore" etc). Is there a facebook unblocker that will unblock it AND let me use those important little buttons?

Recently recieved a job offer but am unsure about the title? It is in market research and involves primarily social media marketing but also other online PR/marketing strategies. What are some typical formal job titles for people doing similar jobs in this field?
