is surfshark's 'nexus' thing any good? do other vpn providers have a similar thing that gives you new ip for every link/webpage you click?

at the end of this video guy talks about it https://www.nsfwyoutube.com/watch?v=uSGVk2KVokQ

i was talking with my brother about removing your phone number form social media accounts but on some websites when you remove the phone number it stays in the history logs on your account (instagram)

is this legal for a website to keep your number in the logs when you deleted it from the account?

nsfwyoutube.com works, but invidious doesnt, good replacement?
