What to do with non-English articles?

I'm not sure what to do with these, though I've only found one so far. I can't really vote when I can't even understand anything, so should I mark this as plagiarized/spam articles or give all positive feedback? I won't bother with google translate if I don't know what language it is.

Dude... Dont mark them spam.... It can cause exp reduction

I'm not revealing any personal details here, so please don't spam.

@Pigeon04 That's why I'm asking. I don't have the heart to mark them spam anyway, but I really don't know what to do when I don't understand what they're writing.

mark the non-english articles (and comments) as spam.majority of this community knows english at common,but only a little part doesnt.they shouldnt be sending articles that literally no one understand(and actually,most of them look like spam)

If the article is not in English you have two choices. Either mark it as spam or you can just give it a thumbs down.

I marked that last one article as spam, because I have absolutely no clue what language it was. I'll be marking them as spam next time too, after reading more from you guys.

Every article can be written again! Except for spam article, it will take down auto by the system and user can't submit that kind of article again! You should thumb down for everyone that not good, it is good then push the spam button except spammer.
