why is yay referred to as y0y now ?

Genuine question as I don't follow all the drama related to yay, what's the reason behind most people on this forum writing his name as y0y instead of yay now?
Is it because of "0" in y0y kind of them trying to imply he's a washed player now?

0 Is to say that he hasnt won a single series since McE. (the c9 coach) cut him from c9

y0y

0 is to represent on his current confidence

y0y

he didnt win anything last year and has the longest red carpet of all time. y0y KEKW

"0" as in "0" wins in over a year
"0" as in "0"-13 loss streak
"0" as in "0" impact in his team
"0" as in "0".xx rating in the past 3 months
and so on

thought it was just a way to make fun of a player like d0rke or t0nz
