Why is this ok?
And tanks are balanced?!? Bullshit.

It's Lollipoppy. That player has seen some stuff to pick THAT skin.
Let's break down your video though:
Poppy's build:





Total: 255 Bonus Armor. 1000 Bonus Health. And a GA.
Armor scales into Iceborn's slow radius.
I don't recall if Corrupting applies on Sunfire's effect, but she had red buff too.
Poppy's first minor heal is at about 1 second in for 41 health. (Grasp of the Undying) Next is 477 from Redemption. That's a jacked up support. (Soraka actually.) She pops Corrupting Potion possibly twice, while you run past raptors. Her Dreadnought builds up as you make that run. She gets her shield for 20% of her Max HP. You land in the wolf pit. She gets her Shield again and it looks like a heal from probably Soraka. Soraka was running Windspeaker's, every heal from her gave Poppy more armor. And then Kha joins in to seal the deal by full-wiping your health via you being isolated and him building lethality.
I didn't explicitly see the exact moments of the Grasp heals, but it applied to Poppy no less than 5 more times in your 43 seconds.
Without the Soraka, I think the Poppy wouldn't have done quite as well.
You did have Last Whisper, which meant that your hits did something to Poppy, but most of her dps was loaded into her passive burns and she stunned you about 4 times over the course. Her whole focus was just slowing you down to stay in range, which means that if you could have 1v1'd her, you probably would have won in larger part, except maybe Soraka's ultimate healing Poppy again or an ally joining in against you.
To reply to your question: Tanks are not balanced. That's why they're getting the next class overhaul.
You're totally right, this is not ok that you recorded your computer screen with a camera. WE FOUGHT SO HARD FOR REPLAYS AND THIS IS HOW YOU REPAY US???
And yeah, everyone knows that tanks have been unbalanced since the Juggernaut update. Calm down, Yas player.
LOL you deserved to die, you tryed to 1v1 a tank... Let alone a poppy that is what she is supposed to do shut down champs like riven and yosuo
Where was your life steal and armor pen? you seem to have not built any, otherwise you might have actually been able to do something useful, or lethality since it counters so much armor for almost no gold...Imo for that, build path would have been
and either
or 
Found the idiot who doesn't known how to use the Replay function, especially when the record button is right there.
Takes out the tower, gets caught into a lucky Poppy stun, still able to 1v1. Soraka intervenes with a heal, you run away, farm wraiths while running away, get stunned again into a wall because you are fighting in an area that favours Poppy. You then both use a blasting plant over the wall. You continue to 1v1 and get stunned with the team showing up to help. From what I can see with this clip. Poppy and Yasuo are both bullshit.
You didn't ult her until her team showed up to kill you.
Like... what do you even expect? You would have destroyed her if you ulted anywhere in the first 30 seconds. Also, Poppy =/= all tanks.
You didn't ult so you didn't get your armor pen, what were you expecting?
edit: nvm lol
Can we see what items you had? I think botr would have been very effective in this game. Or at least LDR.
It doesn't matter if you're bad at the game.

These two Items Build on Yasuo can literally out trade her at mid-late game
Don't calm down, you're right. Riot want's to have bans and unbalanced champs. Take out the bans, and fix the champs.
