Boosting in 2k19

So, short story . I am a friend with someone whos getting boosted , first by duoing but i guess the booster realised she's heavy to carry he used her own account . We realised it wasnt her playing because she used to have bad kda on usual supp and unless she became faker in one night there was no way she can katarina/riven mid with more than 15 kills and less than 4 deaths. Now bare with me .. we know the booster he's in high plat and he played with us few normals with his smurfs and he did say he boosts acc for money ,and she keeps saying that her jump from b3 to s1 was just her changing roles and carrying . Dramas aside we made her play kata and exactly she showed us the glorious 2/14 gameplay. I was reminded with this story when i went to my soloq today and admittedly our mid was boosted/ bought account . Honestly its ruining the experience , its not fun if u dont pick up the tricks by urself and its not all about the elo. Right ?
