Wikipedia:Teachers can be vandals too

Wikipedia does not welcome the bright folks having dreamt up an innovative way to show the world how unreliable it is. They differ from other witty types (students, friends of gays, men with enormous equipment, and asdfghjklms), because they are armed with the iron-clad excuse that they are teachers, not vandals.

2010
In 2010 a French teacher set out to edit the French Wikipedia as part of a broader campaign about a poem by Charles de Vion d'Alibray (including online mock commentaries). He intended to demonstrate that pupils depend on the Internet to do their homework and that many websites are unreliable. The "fun little experiment" was related on his blog in 2012, and received media coverage.

Wangenra
In October 2015, user Wangenra, claiming to be a teacher at Aloha High School, repeatedly edited the school's article to show "how easily entries can be changed". They were issued a "ludicrous" block which led to a horse-caressing discussion at AN/I.

The case shows some excuses that you can use to prevent edits from being reverted, such as:
 * Doing this as a class exercise on source citation/evaluation.
 * This is an exercise on why your site is not allowed as a research option for my writing students...
 * This is me demonstrating to my class how easily entries can be changed.
 * One last time this semester showing my students why I don't want them citing Wikipedia.

Aysedune
The former article Themes and analysis of No Country for Old Men (film) was tagged with, and listed at Copyright problems for review. User Aysedune deleted the template (which states it should not be removed), and was dismayed when an admin restored it: "'That was a good compilation and I always advise my students to read that page. When I realised it wasn't there any more and after learning I could take it back, I did it.'"
