Social networking ethics

[aninditasen]

We all use the social network to share ideas, photos, news, messages and chat too. However some unethical people use social sites like Facebook and Instagram to load obscene pictures or put up job ads that are scams but there isn't any option in our hands to delete such pictures or block scammers and neither do the admin team of these sites monitor such unethical acts. Don't you think we user should get some option to delete such unethical things?
