More than once I have come across terrible servers that fail to do their job. Also, since torrent is illegal, very often such sites are blocked. What to do?

The main thing in this case is to find a good torrent site, but it is not so easy. The torrent must have good speed, be virus-free, and do its job clearly. At the pirate bay, you can find an excellent torrent site (and more) that does a great job, and the risks of this site being blocked are minimal. So I suggest you consider this option. But still do not forget that this is piracy, and that such servers may well provide problems

Features to protect users: the site should be afloat for at least 5 years, there should be no ads, all torrent files should be verified. ...
Variety: make sure that the site's library has content of different kinds. ...
Proven over the years: the more years a site is, the more reliable it is.
