I'm a privacy concerned vpn user and in my daily browsing I have to deal dozens of times a day with cloudflare captchas or in some cases with cloudflare total blocking.
I have the same situation, without manual actions in webmaster tools my website was wiped from search since 5th Dec 2014.
It appears if you search domain.com and if you search site:domain.com but if you search just "domain" it doesn't appears and the website has been more than 10 years well indexed.
I'm very worried because I can't contact google to know what happens because as I said I don't have manual penalties to reconsider and I'm losing my own users that search for the domain.
