Have logged in to stop this from happening and currently apparently I'm "Open to discussing new opportunities", which is news to me. On trying to change it to "Not interested in any new opportunities" there's a dropdown that says "I’d be open to new opportunities in:" and most you can set it to is 2 years. These are whole new dark patterns.
UPDATE You can turn off the setting they're talking about by going to [0] and then clicking the little grey "Visibility settings" under the Profile URL section.
UPDATE There's a delete your account option on this page [1], though YMMV:
>> Government identification may be required and we may ask you for more information in order to verify your identify
Same issue as I'm currently having with Airbnb. Though I have never ever provided any ID before, nor did I ever book anything, they asked me for an ID to prove my identity upon requesting account removal. How exactly does my ID _prove_ anything in my case (apart from the fact that I have an ID copy of a person who has the same name as I entered into the Airbnb profile page). Seems more like one more obstacle to prevent people from deleting their account.
Companies ideally want to stop fraud at both ends, but I would be more upset if, for example, my Airbnb account were fraudulently deleted than if someone fraudulently made one in my name.
Granted, deletion requires access to the account in question, so maybe that's enough of a hurdle already? In that sense it's already harder to delete than create.
