Removing external link from an english webpage 

Hello Mr. Andrei Stroe,
Can i ask you on what base you have categorized my link addition as "spam" ?
I have read all the articles related with external links policy and spam on Wikipedia and i couldn't find a similitude between my adding and any of the Wikipedia definition.
Can you please explain me on which base you did and what means in "your definition"  - "spam".
Let's not over react in the cases where we shouldn't.
I'm kindly wait for a professional (and with quote from Wikipedia policy) answer from your side.
