I agree - a warning of the dangers of visiting infected onion sites
could be useful (even though the problem is not specifically a Tor
one). There's the risk of feature creep - security is a big space and
it isn't really Tor's job to educate people on every risk online.
Perhaps a clarification that just as TBB is not all you need to
maintain privacy, it's also not all you need to stay secure, with a
pointer to some external tips?

For onion site operators, there's this:
https://www.torproject.org/docs/tor-hidden-service.html.en

Which does include this: 'Hidden services operators need to practice
proper operational security and system administration to maintain
security. For some security suggestions please make sure you read over
Riseup's "Tor hidden services best practices" document.'

Which in turn links here:
https://help.riseup.net/en/security/network-security/tor/onionservices-best-practices

That's more specifically about Tor config though - it could usefully
include pointers on basic webserver opsec too, though again it may be
out of scope to say much more than "bad people may attack your web
server, onion or not. Educate yourself on keeping it secure".
