Ban Discussion

I got banned from playing competitive+chatting for 72 hours. The reason? Absolutely no reason. But my teammate, who teammed with the enemy, took the spike, friendly fired us, and trashtalked the whole game, didn't get banned. I have 3 things in mind that may got me banned that I said in chat: 1. "First message: Jokes over." - Second message: "You are dead" I said this seperately after the enemy phoenix ult, then the enemy team said in chat "reported for threats". 2. "I will open 100 tickets if needed, so your account will get exploded." after I got mad that my enemies and my teammate teammed together after everyone died, and trolled with him. 3. "You are calling my family and friends rap!$t" - I said that after my enemy team said that my country does that to people. 4. "Fr3e 1srael" - I said this as a joke at the end of the game, because there was a kid at my team who kept saying in voice that "fr33 pal3$tine" (He was the troller that Im talking about.) I got the ban literally 20 seconds after the game ended, I feel like it was an auto ban by the system. And now I need to open a ticket, and wait 1 day for a response just to get a yap from someone and maybe even get my ban not pulled at all.
