How to delete old data Whois scrapped

I found some old whois data on me on these two sites:
https://gb.bizin.eu/
http://ufind.name

I have tried to find the coordinates of each of them and there are very few of them. Just an email address for one, which bounced.

What can I do? I did this for the .UK webistes through Nominet who were reasonably helpful. What about .eu and .name sites? Who are ICANN and can they help? https://www.icann.org/

It is rather doubtful that websites can still function in this way and be totally impossible to report and contact. What do you think?
