Because you have never been considered as "good" by this "PVP Community". Everybody knows how you got your top 3, by qing into bots at 6AM, there are dozens of screenshots proving it (but I can't post them here ofc). And when ppl see you playing "legit" in Solo Ranked (like in season 10 where you didn't manage to get anything), they realize how you are just average (not saying you are bad, but you are still doing tons of mistakes).
The botted top 3 + your average gameplay + the fact you are often whining about "wintrade everywhere" when there are just bad players getting globalled (wintrader complaining about wintrade xd) are the main reasons why you aren't part of this "Community" as u like to call it.
