[Q] Perma after 1 report?

I got banned for 2 weeks recently because of inting. I completely understand why I got banned and I'm not whining about it. But now I'm really scared to play the game because I don't know what I can get banned for. Do I get permabanned after 1 report just because a troll decides to rep for picking something out of meta or just having a bad day? Will I get permabanned after leaving or dodging (or not connecting because of client) just 1 game? How long does it take to get out of the "penalty box"? What is a complete no-go after receiving a 14-Day ban(besides to continue to int) Edit: deleted my advice that others may find controversial
