Seriously, this rule cannot stave off trolls. The trolls can read this rule and try to get a workaround to this rule. It is easy to gain one edit, by just editing the profile or by commenting or whatsoever. Although trolls in chat mainly do not edit in mainspace, this rule cannot hamper the number of trolls in chat. Worse, the edit can encourage trolls to troll in mainspace, causing another set of problems.

I may see this rule more damage-prone rather than damage-resistant.
