 Sources 

Sources need to specifically discuss the subject. When you use books, you need to include the page number(s). Exactly what does Charu C. Aggarwal (2011). ""Social Network Data Analytics say about ""social network poisoning""? What exactly does it say about ""considerable impact in terms of knowledge and correlation of data""? I need page numbers and quotes. Please note that you can't interpret a source - you may need to read WP:NOR and WP:VERIFY. You probably aren't used to policies and guidelines here. And you need to read WP:AGF as your edit summary looks insulting.   "
