It’s not more risky than torrenting yourself, it is just not risk free. If you live in a country where torrenting is safe: great for you! It’s not like that everywhere.
Regarding the entire issue: Usenet and Debrid are extremely uncommon and “underground” compared to regular torrents or direct downloads. The lobby does not have infinite resources so they target the big and easy to catch fish. Just harvesting torrent IPs and suing individuals with zero knowledge of defending themselves is super easy.
