And this is one of the many reasons that these days I create a @duck.com email address for each website.

My password manager (Bitwarden) happily generates for me both the mail and the password… now instead of having to look up for the unique password for each website I need to look for both the unique password and unique email 🤷

Furthermore if they are incompetent enough to make shitty regexp they are for sure incompetent to keep their db safe from hacking/leaking… and I am fine with a duck.com address being locked, less so with my actual email address
