Why don't nfo files contain a checksum for the release? (lemmy.dbzer0.com)

I assume there's some historical reason for this, but currently, the way scene releases reach most people seems to consist of:

Sites that track releases post the nfo file of the release; these sites generally don't provide the release itself.
People then look for the release via various channels and download it.

Wouldn't it make sense for the nfo to contain the checksum of the actual release, letting pirates verify unmodified copies of it and making it easier to avoid versions that have been modified in various ways?

Obviously you'd still have to trust both the site where you got the NFO (and therefore the checksum) and the people who made the original release, but those are usually relatively trustworthy, being known people who have handled a lot of releases with no problems - a lot of the danger of viruses and the like in software piracy comes from the risk of middlemen adding something.

Uh... If they messed with the iso, they could very easily mess with the NFO

Yes, I mentioned that - but trusted public sources, who often post on places like Reddit or personal websites run out of the US and the like, can post NFOs but can't post the actual game. If you knew the correct checksum, you could then turn around and grab the game from an untrusted source.

Distributing the game itself is the dangerous part (in terms of making the copyright pinkertons come after you) so it's better if it can be done as anonymously as possible, but that conflicts with the need to have it distributed by someone trusted. Putting the checksum in the nfo, which is widely reposted by trusted sources, would help avoid this problem.
