Hotels unilaterally ask for ID and a credit card these days.

Some (ok, maybe most) hotels ask for an ID when you check in.

But I've never been to a hotel that asked for an ID just to make a reservation. I use booking.com, which is perfect BTW, and they never asked for an ID.

It's hard to imagine how a hotel could bilaterally ask you for your ID :-)

And in any case, they don't ask you for a Facebook or LinkedIn account to spam you with besides your ID and credit card.

Yes, the equivalent would be your host asking to see your ID upon arrival. I don't think people have an issue sharing their identity with a single other person. A soulless corporation on the other hand...

Which is nothing compared to social media accounts and a credit check.

Yes, but in person. They are not asking you to upload it online... something few people have ever done.
