Has anyone else been signed up to Orbitz without actually doing so?

The other day I got an email saying thanks for creating an Orbitz account, which went straight to the spam folder, as such I ignored it. Today I get a newsletter from them, so I tried the forgotten password link and reset my password. There is basically no account information, apart from a name of 'Alyssa Day'. My email address is fairly unique as I have my own domain, not likely a typo.

Has anyone else seen this with their own email accounts?
