A few (new) users have unusual names like "LaTeX" or "google".
I personally think we should not allow such names i.e. tell this users to rename their accounts, because they are just confusing in comments. Imagine someone writes "The solution given by LaTeX" or "As stated by google" inside a comment.
I think users should not be named using "reserved keywords" (like they would be called in a programming language), i.e. TeX executables, package names and TeX primitives as well as well known software or web applications.
