24 alternatives to No more writing shitty regexes to police usernames
Every product that allows usernames eventually ships the same broken solution. Someone adds a blacklist. Then a regex. Then another regex copied from StackOverflow. It works just long enough to ship, and then `admin`, `support`, city names, brand impersonation, and obvious slurs start leaking through anyway. Everyone knows it’s fragile, but it gets ignored because "it’s just usernames". I’ve had to rebuild this logic across multiple products, and I got tired of pretending it’s a solved problem.

Would love your honest thoughts.

It confirmed several users who I suspected were alts and after informally asking around has identified abandoned accounts of people I know from many years ago. I made this site mostly to show how easy this is and how it can erode online privacy. If some guy with a little bit of Python, and $8 to rent a decent dedicated server for a day can make this, imagine what a company with millions of dollars and a couple dozen PhD linguists could do.
