Anyone actually removing site from google search successfully?

Yes, but the Removals tool in search console on its own isn't it. That only hides URLs for about six months, then they come back if nothing changed. For permanent: put a noindex on the pages (or return 404/410, or put it behind a password), and leave them crawlable until they drop out. The common mistake is blocking everything in robots.txt first, then Google can't see the noindex and keeps the URLs listed anyway. Use the Removals tool alongside that if you need it gone quickly.
