Now, the way the original author responded is completely inappropriate given WP:DNB (en.wikipedia.org/wiki/Wikipedia:BITE). A couple people have already tried having that conversation with the author, and he/she still incorrectly feels the onus is on the (naive) editor.

Obviously the deleted material, that is, everything that the student previously contributed, contained the citations (on the left). Still everything was deleted by the strange behaving wikipedian.
The difference I link to shows the effects of the second deletion of the student's newly contributed material by the wikipedian. How can that be justified? I understand that the wikipedian didn't want the original research. But was it all really just the original research?
