Any cause you might have had for the board regulars to upvote and support this thread is evaporating rapidly as long as you keep insulting people for pointing out oddities and asking questions.
Your excuse that you were outplayed by higher-ranking people doesn't seem to hold up. High-ranking opponents only show up in two of the four games offered, and in neither of those games was that opponent the one laning against you or carrying against your team.
The Shen game seems like the biggest offender of the bunch. Taking Shen mid in the first place is a questionable choice, but you then proceed to start dagger/refillable and rush straight for Swiftness boots, a bizarre choice that I don't see reflected in your other games. Dying a whopping 19 times, only getting 89 cs in a 35 minute game, and building in a way that I can honestly say I've never seen a Shen built all push the narrative that you were intentionally throwing that game.
Secondly, the Hecarim game. I can't comment on bringing Hec to the bot lane due to how weird botlane meta is right now, but again, you rush swiftness boots, get almost zero damage/cs, and die about as often as one could within the allotted time. The fact that you purchased a ruby crystal after your t2 boots, then sold it to purchase a Zeal, suggests troll-building. Your support only died twice, suggesting you were fighting well out of his range, since in a 2v2 all-in situation Ivern lacks escapes and would likely have a hard time surviving what a Hecarim couldn't. He also dealt nearly twice your damage to champions, despite being a support Ivern.
I don't see much wrong with the other two games. Maybe you inted one kill in them. Maybe you were just reported for them and they were included in your card, while the Hec and Shen games were 99.9% of the reason for your suspension.
If you truly maintain your innocence, submit a respectful support ticket and get an explanation and second opinion. Feel free to share the result of that ticket with this thread.
