While easy to do, issue with doing this is you don't give active views to the lists that get combine so the owners of those lists are less inclined to update/maintain them. I would recommend if the list is useful to get each of the combine lists he uses and add them all separately.
Tokio specifically says not to use it for CPU intensive tasks and rayon would be better for this: https://tokio.rs/tokio/tutorial
Speeding up CPU-bound computations by running them in parallel on several threads. Tokio is designed for IO-bound applications where each individual task spends most of its time waiting for IO. If the only thing your application does is run computations in parallel, you should be using rayon. That said, it is still possible to "mix & match" if you need to do both. See this blog post for a practical example
Can you even trust Topton from a security perspective compared to we'll know brands to not have firmware that installs backdoor or have a built in backdoor in the bios?
Quicker to just throw it in the fire place... ya know?
