Using a catch-all domain is a mistake
I'm using catch all since forever. I regret nothing.<p>Two stories:<p>I don't use mails like facebook@domain uber@domain - that's too obvious. And knowing that may often disclose that I actually have an account registered on given page. I don't want that, so I go full random, using few words I have in mind, current few words from the song I'm listening too, etc. So password manager helps me with e-mails too.<p>But Sometimes when a website annoys me (stupid rules for passwords, crippled UX for forms, because re-writing a select component in javascript is such a brilliant idea, etc) I tend to insult the company I'm registering with using my e-mail or password, I mean mail: this.freaking.store.is.dumb@domain.com and pass: goDieInPain1312323$$$$. Once I registered account for a supermarket loyality card with some very little insult towards the supermarket. Later I got some huge amount of the points collected and their system crashed and I had to contact the support (the bonus was too high for me to give up on that). First via e-mail then via phone, when they were confirming my address. They helped me and said nothing about the name I was using.<p>Another story:<p>When I started with catch-all I was actually using mails like companyname@mydomain, and when I once contacted them via phone the person talking with me was not very into tech I think and were accusing me of... I don't really know exactly, but she told me something about me using their stuff without their acceptance, when I tried to explain that's my own domain she told me I cannot use their name, because that's a copyright infringement. Weird.
