I am sure if someone from the forum with that amount, we won't be bothered to think of more and what's enough is enough.

He's the new version of "Inverse Cramer" where investors are going the opposite of what he's saying. In this case, traders are going the opposite of what his position is hence, him losing significant amounts of money these past few weeks.
That's putting it a bit harshly. Cramer gets his calls not only consistently wrong, but crucially, consistently opposite. It's like CNBC only pays him for the TradFi memes now.
I'm think that there might be some retail traders out there that made money just by positioning themselves the opposite of what this trader is doing. As for his account being deactivated though, I'm pretty sure many will just forget him in just a few weeks to a month, but he's a perfect lesson to those traders and aspiring traders like you said. Traders, and those aspiring ones should know how risky trading is particularly leverage trading. In his losses, he always go for x40 leverage which is very risky, and we know what happened to him.
When you leave, the internet tends to forget about you very quickly. You become something of a fable but that's it.
TBH, I learned from his losses and since then, I minimize my leverage especially when it comes to altcoins. Usually, I always go for around x10-x15 or even x20, but now, I always go on x5 only, and for Bitcoin, around x20. There might be saying that it's too high, but I know the risks so... yeah. 
x5 in my opinion is still way too much, as many cryptos regularly pump or dump more than 20% from any given time.
