Wikifascist 

(n) - a trolling wikipedia editor who deletes an entry because a 30 second Google search confirmed their sneaking suspicion that such an entry simply Must be fraudulent.

"I posted the newly-discovered Theory of General Relativity on Wikipedia, and some Wikifascist erased it claiming vandalism!"

Wikifascist 

An individual who utilises their knowledge of Wikipedia's rules and policies in a strictly-defined fashion to bully, harass, or override less-knowledgeable contributors with zero consultation, frequently deleting their in-good-faith efforts to improve wikipedia, in direct contravention of the spirit and often the letter of wikipedia.

I spent some weeks creating a well-researched highly-technical wikipedia entry that was missing, and was just in the process of linking it to well-known pages and was adding references that would help make it "Notable", when some Wikifascist deleted with zero notice or discussion
