Scrooge MacDuck is one of the Scrooge McDuck Wiki's admins and bureaucrats. The "rule six" referenced can be found in the guidelines for this wiki's Discuss. It currently reads as thus, "For the love of Walt, use proper spelling and capitalization. In other words, "yu r not allowd to spel like ths". Never, not in a million years. If an admin calls you out on this and you do not correct your post, this may result in blocks, as it would be considered spamming and thus fall under Rule 4." Rule 4 currently reads, "Voluntary spamming, trolling, or vandalizing of any kind is of course forbidden and will be deleted. A post whose sole purpose is asking for upvotes is considered 'trolling'."
If you have any issues with the rules or with Scrooge MacDuck's conduct in his capacity as an administrator and bureaucrat, please message him civilly. Calling someone a jerk really isn't the definition of civil and polite. If the post-locking bugs you so much, I'd recommend civilly and politely messaging Scrooge MacDuck, taking the issue directly to him instead of complaining, name-calling, and lobbing personal attacks and insults.
@TheMidgetMoose what if someone is bad at spelling. And that guy removed peoples posts because they were not accurate. He got rid of someone’s poll because he said Ducktales 2017 vs Ducktales vs Ducktales treasure of the lost lamp, because he said that Ducktales and the movie are the same (which is true) but he deleted it!! He even did more things like that.
