Hi,
It`s clear that torrenting is a categorized process, but as well there are torrents are bad for health, they are Untrusted and Malicious trackers

here is a list of those

https://www.homeporntorrents.club/register.php
https://hidden-palace.xyz/signup.php
https://www.devils-playground.org/signup.php
https://www.nbytez.me/signup.php

so if anything opened with you, I recommend NOT to report it, it seemed it`s a shitty tracker.

What makes them malicious?
