Hello!
To start my attempt at not lurking I am posting a link to the collection of links I have from Reddit regarding various Piracy sites. Please keep in mind this is my personal collection. You should ABSOLUTELY vet the links yourself. I am just a guy on the internet, I am not a trusted source.
This is not a complete list. This is just the sites I refer to for their specific category. I've omitted a fair bit too since the megathreads / link collections have them already too.
Seriously, setting up streaming with Real Debrid and Kodi add-ons was one of the best decisions I've ever made. I have gotten through a huge chunk of my watch-list since.
Eh, I did try it, and can see why some might prefer it, but I spent a fair amount of time configuring my Kodi setup perfectly with my Trakt lists and a nice skin. It just works the best for my use case.
I'm intrigued by Syncler though, even if you have to pay. That plus what I already pay for RD would still end up massively cheaper than what everyone I know pays for a single streaming service nowadays. I'm still surprised more people haven't turned to piracy in the past few years of proliferation of massive amounts of new streaming services and crackdowns on account sharing.
