I don’t think the op was talking specifically to the content author, but to all the people who read the article and get the idea to scrape Wikipedia.
(Before anyone takes this out of context - no im not saying its ok to be intentionally disruptive, or do things without exercising any care at all. Also always set a unique descriptive user-agent with an email address if you're doing anything automated on wikipedia).
It’s incredibly easy for careless scrapers to disrupt a site and cost real money without having a clue what they’re doing.
I want people to think twice and consider what they are doing before they scrape a site.
