If you mean
this, you got the warning not for doubleposting but for your immaturely disdainful attitude.
First off, you don't make 1-emoji responses, especially not one telling "i don't care / go away". But, on top, you even added a very supercilious "don't talk to me like that" when all what people did was
friendly advising you.
It's not the first time telling you that you have a dissocial personality. You paranoidly feel attacked by people responding you and you're being unthankful and spiteful even when people are completely friendly to you.
You take criticism too personally and sometimes sense criticism even when it's not. Your signature is spiteful and your current flair is ... quite cynical?
So if you say "I don't want to do anything wrong", this is my answer for you.
