I'm still new to PBN's and I'm not sure how paranoid is being too paranoid with regards to google. I may need to access webmaster tools at some point, and I'd like to use Google Analytics as well. All my sites are sitting behind cloudflare, but should I be worried about how I log into my google accounts that are attached to these domains? At the moment I have proxies setup for each individual account, and only access these accounts in a browser behind their respective proxy. Is this all actually necessary, does Google log account IP's and cross reference them?
