(Original author here). Yes I am aware of the identifiers that are sold through a third party data provider. Reading further, I also note that I decided not to care if Disneyland knows that I went, it was more about continuing to obfuscate my family, so I decided that was a risk I would accept. Of course, YMMV.
Curious why you consider D+ asking for birthday and gender to be deal breakers? Why would you even consider providing real data to those question? Just simply make up a name, birthday and gender. That's what I do.
It's not a dealbreaker for practical reasons, it's for moral ones. I don't think they should even ask for or collect that data, given the ability to de-anonymize that the additional information provides them. They don't need it and shouldn't ask. Especially as most people don't know they can just make stuff up, and never do.
I'm with you, I make up email addresses, mail addresses, credit card numbers, pseudonyms, genders, birthdates etc...
