> To me having several pseudonyms and also using throwaways is part of standard information hygiene. I also have multiple email addresses, some are set to forward to others (one-way of course), others aren't. I don't know why people aren't teaching that to their children.

For aliens (people entering under ESTA, visas, etc), you are compelled to reveal any aliases or pseudonyms you operate under. There's a two page document for you to fill the details out under ESTA, presumably under under a visa as well. Lying to a border guard, or on these forms is a felony.

That must be new. It wasn't part of esta two years ago. I would be totally unable to produce all my aliases in all the services I have accounts. I wouldn't even be able to remember all the services.

I believe it's supposed to be only names you've gone under, calling yourself horsemaster88 on youtube wouldn't be included, but calling yourself Jerry Fink, lord of horses would be included. With the new laws going into place for giving up social media names I wouldn't be surprised if online pseudonyms will be included in the future though.
