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.
If your looking for a music tracker, the best private tracker for flac files is redacted. they have a huge collection. its a private tracker but its pretty easy to get on as long as you care about music.
Not sure I'd say RED is easy to get into... and its definitely not for newbies to private trackers. I'd suggest Orpheus as being easier to get into, more welcoming to newbies... and easier to maintain ratio.
