General DiscussionBehaviour score problem

when i am 1k - 3k my behaviour score always 9k++ (just some rare case when i have a blackout and abandon then get 7k behaviour score)
then since i'm 4k and have the 4k-feeling-pro syndrom (actually no one got higher mmr than me in my school, so hard to avoid feeling-pro syndrom) i start to trashtalk whenver i playing with my friend
lately i play party with my friend (which is 2k 3k) i usually trash talk everywhere anywhere losing or winning.
no matter that's my party or my enemy
and i always rape f9 button if someone dc (even my teammates sometimes)
then everyone reported me
i rarely play solo because always playin around with my friend now
when i play solo. the game quality so fucking low and everyone is toxic
my behaviour score now its almost same as my mmr (the fuck)

VALVE MUST SEPARATES THE BEHAVIOUR SCORE IN PARTY AND SOLO QUEUE
I CAN'T HANDLE MY TOXICITY IN PARTY QUEUE
Because when i play solo match i always PMA and keep the anger to myself
notice me valve. ty.

Also, when we report someone pls dont make us team with them again
