Registry intervention isn't that common, unless it affects the domain name itself.

I think the two most common encounters would be UDPR cases and government take down demands. I don't think any TLD owner will bend over backwards to protect the registrant in cases like this. They will just comply and move on.

For Google, though, the worst I imagine is their TLD nameservers using their logs to rank your domains for search results.
