What is illegal with anime that can be downloaded? It is not illegal to distribute anime that is not licensed in the US if you don't know.
Yes, CRC checking is slow. It is especially slow when running other processes. It is slow even when not doing those other things. Running it on a 200-700 mb file can take 30 seconds to 3 minutes. It would be impossible to download/upload during that time. Why do you think I posted a request to allow threading?
