Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

I think there's a variety of complex legal, political, and technical reasons why torrent sites can avoid having their domain "seized", but I think the summary is: there be dragons here and it's not worth playing around with.

Politically, some jurisdictions define piracy differently and hosts won't comply with legal threats from the US.

Legally, hosting a torrent is not the same as hosting a ROM. In the former case the actual copyright works are hosted by users, the torrent site just hosts the torrent file which is a list of users from whom you can download the content. ROM sites tend to provide the actual file for download, which contravenes relevant copyright laws.

Technically, you don't need a commercial host platform to operate a website. It's entirely possible to host a site in your mum's basement on your laptop. Obviously for a large site you'll want more appropriate hardware but the point is larger torrent sites are likely to run on hardware maintained directly by the admins.

The most compelling reason not to get involved in a public facing grey area site like ROM or abandonware hosting, is that it doesn't really matter where you stand with the law - you won't have the resources to defend yourself. Suppose Nintendo decides they don't like you doing what you're doing. They have an army of sophisticated lawyers who have spent a lifetime learning how to weaponise the law. It doesn't really matter who's "right", all that matters is how much money you have with which to engage lawyers to defend yourself.

These days, torrents are honestly not as big of an issue from IP holders perspective as you would think.

In the mid 2000s, torrents accounted for 30% to 50% of all internet traffic (with higher share during peak hours). It was a big deal.

Nowadays, there are other priorities and torrents are seen as less pressing challenge.

A lot of torrent sites are on cloudflare. The IP owners are less balls to the wall than you'd think for non-sports content because it loses money anyway and more exposure potentially makes money in terms of expanding the brand long term.

From what I've read, usually "DMCA ignored" hosting in a country like Russia acting as a proxy to the main (cheaper) server.

Njalla for domain registration

Nintendo is a special case. Their entire business model is based around their first-party games only being available on their systems. As a result, piracy is a much much bigger threat to their business model than it is to anyone else.

(Beyond that I feel that there's a cultural thing where the people calling the shots at Nintendo just hate piracy a lot more than most other companies - they've always been weirdly aggressive about it. But it's not totally irrational - they really depend hard on games like BotW only being available on their systems.)
