I do not know why you fear that your social media would influence your credit score. Unless you are actively tweeting out your credit card information it does not concern them in the slightest. Do note that it can hurt your chances of getting a job (especially if you post negative stuff) which I guess can indirectly impact your credit score.
No. Social media activities aren't reported to the credit bureaus and more importantly, they do not factor in the determination of credit scores.
