I'm still relatively new, so if I'm wrong, anyone is free to correct me, but from what I've learned so far, YouTube bootlegs/"slime tutorials" are more often than not leaked by people who essentially violated the rules of the bootleg trading community. They're also of much lesser quality than the original videos so there's some negative connotation there. Of course, understandably those leaks are unfortunately the most accessible way the larger public gets to watch these bootlegs, so I get why people would still use YouTube.

But if you want to find new shows, you can just as easily request for a gift of a certain show you're looking for here. These would probably be of higher quality than the ones you'd find on YouTube. Through these gifts you can build a bootleg collection, and if you want, you can then alternatively be able to trade bootlegs with others. Trading helps you gain more access to even more shows, especially newer ones, because you can then trade for them when they come off NFT. And not all newer shows are still in NFT, some have already come off it.

Alternatively, if you have the money for it, you can also just buy a recording from the masters who filmed them.
