You have great advice here!
Yes, and your smart "free trial" idea really eliminates any (perceived) barriers for an individual to download this series on the other torrent sites. And as bbb noted, the sites mentioned here don't require membership, though you'll need to close some ad windows, and those can be shut down by using a VPN.
Maintaining a VPN would run about, say, $3 a month (dividing by an annual subscription) for the peace of mind that ALL of one's downloads, wherever, are anonymized. There must be dozens of threads and comments here (many by trusted Moderators) that explain the benefits of a VPN, and recommendations of particular brands. It's hard to reason why any thoughtful person would be so resistant.
