If they have a "delete profile" button that works, then recruiters shouldn't be able to scrape that. It doesn't really matter, the country I live in has robust anti-spam and privacy laws. When I lived in the US, I was spammed often (CAN-SPAM is pretty weak compared to GDPR and CASL), but you don't see LinkedIn campaigning for better privacy laws in the US.

Apart from campaigning for GDPR-style protections, there are enough other solutions. For example, GitHub has a nice email forwarding feature to preserve user's privacy/email address.

LinkedIn could provide a similar option where when I opt-in, my email address is replaced by an address they provide. They could even go a step further and make it look like a real email address. Any emails to that address are forwarded to my real address, and after the initial forwarding I could reply from my real email address. Meanwhile LinkedIn could do analysis of who is sending what to these email canaries (like they transparently said they would when you opt in), and catch scrapers that way. For users, if I'm getting too much spam, I can simply request a new canary email address from them.

This is what a user-focussed solution would look like. Not some weird semi-legal hack they are doing now.
