It basically comes down to making sure that the IP address you are downloading the torrent from is not your own.
One way to do this is by using a VPN. The good thing is that you can use your own computer and hard drive space, the bad thing is that the VPN significantly reduces your top speed, and VPNs often throttle torrent traffic at least a little to avoid overloading. This is a pretty cheap option, especially if you're expecting deals. I purchased 3 years of PIA VPN access on Black Friday for $60 total, from Nov 21st to Nov 24th, making the cost per month less than $2.
Another way to do this is a seed box. Seedboxes are basically remote torrent clients, with disk space attached. The good thing is that these are very fast (often up to 20 Gbit/s) and come as complete packages with torrent clients, irc clients for ads, ways to generate automatic download scripts and all you have to do is FTP or HTTPS in the seedbox. and download what you want/need at the maximum speed of your internet connection. The remote host doesn't log ANYTHING, so if an ISP knocks on the door, they just claim they have no proof, which is true. The downside is that there is an expense, they usually START at $15 per month. Mainly because you are using remote CPU power and disk storage. But they keep the torrent protocol out of your home entirely, in case you don't have the best internet connection, and a protocol like that can open too many connections simultaneously, causing problems with other clients.
