Need some help on understanding torrent sites

First and foremost, I really don't know if this is the place to post these kind of threads. I think it's not lol.

I'm a beginner in HTML/CSS/JS/PHP, and I want to start a torrent website.
I know I should grind some more my skills, but I need to know some stuff like: what should I also learn, what to avoid, how risky it is...etc.

I took a look at ThePirateBay, KickassTorrents(clones), 1337x, torrentgalaxy and more, about their design and what languages they used to build their websites. These sites (most of them) don't host the torrent files in their host, they either direct you to another site or give you a magnet link. I read somewhere that they do that to avoid troubles with the law enforcement. While some other sites actually host the files in their host.

My questions are:

1-Most importantly, is it worth it? I know it is a long process to get popular and start making some money
2-What technology should I learn? Or do I need to keep grinding on what I know? (get to learn some frameworks).
3-How risky is to get into trouble? what are the thing I should be aware of?

Thank you!

1) If you're in it for building up your skills while having fun in the process, it's worth it. The process to get popular/make money is long, and if you're in it just for that, then it will seem longer.

2) With some PHP Framework and your knowledge of HTML/CSS you should be able to go. Also with a quick google search I was able to find a list of frameworks for torrent sites/trackers on github:

3) You could get in legal trouble and have to pay huge fines, even go to jail depending on the charges. You should always use VPN to connect to any of the services you use for the site, never pay or get payed with something that can compromise your identity (use bitcoin or cash), never use your personal info for registering for services. I recommend njalla for domain/hosting.

Good luck!
