Rename users with an underscore

We all know that, according to the rfc standard, the use of an underscore character in domain names is unacceptable. Hence, the question is brewing: how will you react (addressing users with such a symbol) to the total renaming of your nicknames to another, which of course is not on the site.

Thus, we will make Habr a little better.

For statistics: users with an underscore in the nickname on the site only 3132. Of these, activated and non-banned - 3062.
