Yes, it works but it is only a workaround in my opinion: treating an url 
string as in mathematics seems wrong to me.

I found no example suggesting to use \_ in \href{}{} or \url{} commands.

I tried with Atom Editor and its language-latex package, and the above 
example (BLA_BLA...) is displayed as expected from me. See attachment.

Anyway, if you think it is OK to use \_, you can close this bug report.
