@fribbledom Rhe first three characters of my email address are “a@9”. Both the one-char user part and the leading digit in the domain screw up a bunch of systems.
I keep trying to report them but nobody I talk to has any idea what I’m talking about. I’ve had a bunch of conversations which come down to “look, just tell an engineer that the regexp on line N of file foo.js is wrong and they’ll know what you’re talking about”.
