Is making a shitcoin and Pump&Dumping it illegal?

I am watching Zero Budget Stories on YouTube and watched “Wojak creates his own shitcoin”. He makes a shitcoin and advertises it all over the web so pump it to like 3000% gains.

My question was: is this not illegal? Possibly market manipulation?

Has anyone ever been charged on a pump&dump in the crypto community? I know that crypto is not regulated like things such as the stock market and such but I was just curious what the ramifications would be if something like that were to actually happen.
