Adduser choses 751, which is wrong IMO, as the directories are still

The directories aren't readable either; their contents may be, but you
can't see what the contents are.
I guess that depends on what a user's definition of a directory being
readable means.
And it sounds a lot like security by obscurity.
~/public_html (probably) won't work with 751, but that's the choice
and problem of the administrator that choses no.
$ mkdir testing; echo 'hi' > testing/hello; chmod 0664 testing/hello; sudo
chown root:root -R testing; sudo chmod 0751 testing;
$ cat testing/hello
hi
$ ls testing
ls: testing: Permission denied
$ sudo chmod 750 testing;
$ cat testing/hello
cat: testing/hello: Permission denied
Any questions?
Yes, do you think 750 or 751 should be used?
Consider the case where a user wants an easy way to ensure that none of
the files in his home directory are world-readable.
