Sigh. "Use of malicious 3rd party programs or modifications to your League of Legends client"

Lol. I don't even know WHAT THIS MEANS. WHAT THE HELL. The only program that ever "interacted" with this stupid game is Curse Voice, and Overwolf. I've spent WEll over 300$, 2000+hours, and way to much stress on this fvkng community to be treated by riot like this. Perm. Suspension. God. What in the world?!!?! I opened a ticket already.. Any advice, experiences, or comments with this? FUll message below:
