A strange question.

So basically i'm scraping Plat 5-Gold 1 and too lazy to play on my main,due to various factors. My bronze 5 friend duo-ed with another friend of mine who is Silver 3 and i wanted to play with them,so they gave me a Silver 5 account to play from and that account is a possession of another friend of mine ( Kind of complicated.) So my question is : Is this considered elo boosting in some kind of a way?
