The spam blacklist does not seem to stop spam from being added to new articles from the article creator. I was stopped by it during RC patrol and blanking a copyvio, and I have evidence via this diff of the spam blacklist circumvention.

The Spam Blacklist does prevent the Article Creator from publishing anything with blacklisted links. I just checked and confirmed it’s working as intended. This link in question just wasn’t on the Blacklist at the time the article was written; it was added 2 hours ago, meaning it was on the list by the time you edited. 

I’ll close this thread since there’s no bug here… if you have questions, feel free to reach out on my talk page. Thanks!
