Are profile pages (about section) required to be written in English?
For example, this Stack Overflow profile that I found is entirely in Italian.
Stack Overflow is an English-only site, and that content needs to be in English has been discussed many times.
The most active meta question about this states:
tl;dr: Unless you're posting on a language-related site (e.g. French Language) or a site where all questions are expected to be in a different language (e.g. Stack Overflow in Spanish), yes, all posts are expected to be in English.
Some more questions that back this: A - B - C - D - E.
All the meta posts talk about questions, answers and/or comments. - They don't seem to discuss profiles, and whether it is alright to have a profile that is partially or entirely in other languages
Unfortunately, I'm unable to find any guideline if this is accepted or not.
As such, is it alright to have non-English profiles, and if not, do I need to do anything about it?
