why do we replace players name vowels with 0

i dont get it

to make fun of them

Its vlr, their way of trashtalk

culture

I think it started with s1mple (haven't seen an example before him), whenever he did bad some would call him s0mple
then this spread to other players in esports with 1 in their name
And in the end it ended up in VLR where we just replace every fucking vowel with a 0

y0y

s0cksyy

Didn't this start in hltv?
