I remember reading a discution about deleting an article because it didn't have encyclopedic information. And this 13 year old kid just creates and article like this.
How is the procedure wikipedia follows to find out about crap articles and change them or remove them?
Update: I didn't expect such a retarded first answer :(
I know Y!A allows everybody to give opinion but...

What I want to know is how with millions of articles, they can detect things like this.

[No, I DIDN'T write the crap in the article]
