Most weird censorship, explain me this please:

So we spoke after the game ( no hate or negativity, just were talking about objectives) and I type in post game "xin 0 dragons" and for w/e reason i got censored, it looked like _ xxxx dragons_ , instead of xin 0 dragons. I tried with other champs but all other champs were ok to write alongside number 0. What's wrong with xin, why it gets censored ?

Does any one have an idea why RIOT hates Xin ?
