Some of the content in the user page on pt.stackoverflow.com is not localized. Here's the text I noticed:

    Thanks for the heads-up, but it's probably a duplicate in this Meta - This kind of question usually done at Stack Overflow em Português meta (same for other languages), also we have a tool, traducir.win to translate such strings (a kind of community "self-service" translation) - Note that from time to time some strings change, so it's (more or less) normal to ocasionally a regional site miss some translations. Also, we have a lot of pending strings due to recent changes. Anyway, it's a valid and useful observation.
