The use of quotes to question the authenticity or true nature of something is accepted in English. You could have said "journalism" and I wouldn't have jumped on you.
On "article" though it's inappropriate. The other comment notwithstanding, an article is an article, no matter if it's written by a journalist, an amateur, or a monkey banging its head on a keyboard. There is zero credibility implied by the word.
Example:
> The "food" from that restaurant was awful
Correct usage. You are (humorously, snarkily) questioning that what you received was food at all.
> The food from that "restaurant" was awful
Incorrect. No matter what you thought of the food, the fact is that it is a restaurant (ie, a place that dispenses food, with no consideration of quality implied). This usage betrays a lack of sophistication and should be avoided.
