The technicalities of usernames and underscores makes this seem more complicated than it really is:
"Without any evidence whatsoever we convicted a man named Joe Smith, because we had been told that there was some man somewhere named Joe Smith, who was suspected of being a criminal."

Europol doesn't do things like that, they're not some kind of police that can conduct investigations. Wikipedia has a summary of what they actually do, in case you'd like to know:
I have heard the term DNS a million times but don't really understand it.
Learn about DNS, it's the glue that holds the internet together, any time you spend on learning more about DNS will quickly pay off. You probably already know that it's what maps domain names to IP addresses and vice versa, but it can be used for loads of other useful things too.
(My own two favourite not well known but totally standardized really convenient things to use DNS for is to provide SSH host key fingerprints through DNSSEC and requesting letsencrypt certificates for host names without any webserver.)
There's something very fishy about this claim, I happen to own a European car from the year 2000 so I just went out to the garage and measured it, just to be sure, and it's still exactly the same length as it was when it was brand new.
I became a dollar billionaire somewhere around fifteen years ago when a friend gave me a 5 billion dollar banknote from the Reserve Bank of Zimbabwe, still legal tender at the time. At that time I was already too old to play in the street like a child, but I still to this very day walk in the street in front of where I live every day.
I grew up long after cars had already become commonplace in our city but we still played in our residential street for drivers had learned to navigate safely around playing children.
Why did you do that?
