I couldn't resist. I took a look at the site.

The domain name and the surface content are infuriating. They create a 
frame with the idea that a regex for email addresses is possible and 

However, at the bottom of the page is a discussion thread. It says 
exactly what I would hope a discussion about "email regex" would say.  
It is dominated by objections to using regex's for anything more than 
the most simple syntax checking. Many people make the point that the 
only way to know if an email address is valid is to send a test message 
to it.

And, if you look at the regex examples in the different programming 
languages, they do different things. That says to me, as a software 
developer, that this is not a serious site. If the site had a really 
good regex, they would try to preserve its merits in all the programming 

So, I think this site is infuriating, but not worth spending much effort 
to correct.
