Very bad practice.

"chown charles.menzes foo" will be interpreted as a request to change
the user owner of foo to "charles", and the group owner to "menzes".  I
wouldn't be surprised if other programs didn't freak out over the
period.

Numerals and underscores, at least, are OK in user names.  It's also
best to keep the username at 8 characters or less if you can, although
this is less of a problem than the problem of "." in the name.
