Well there's no need to really think much about it, but I guess I do subconsciously consider my reputation with them, and thus I always aim to keep my stuff unique and of quality, and do my SEO properly.

Just focus on quality content with good healthy SEO, and you'll naturally be in their good books. Avoid blackhat tactics like the plague.

this is a myth. All evidence i have seen indicates that whois privacy information rests with the registrar that provided the privacy. Google violating whois privacy for reasons beyond being a registrar (purposes of their search engine) would open them up to lawsuits. I see no reason why or how IPs could identify you or all your linking patterns

Depends, some registrars/providers can protect your private data from being displayed publicly under whois. Some offer whois privacy for free while others require an annual fee.


Depending on the laws from the country where you're in, only a court order/summon can compel those isp's/hosts/providers from disclosing your information.
