This is what I do..
Random email hosted at outlook.com
Separate phone - It's a smartphone, gps disabled, google account is created with the above outlook account and all google settings (location, search history etc are disabled)
Remove all social media apps on said phone
Never save messages or call history on said phone - delete that shit pretty quick just in case.
Keep that phone in work.
AW account is registered to the above email. Saying that, all punting activity is linked to that email address.
I use firefox on my main PC and I have it set to clear cache, cookies, etc when the browser is closed. This makes "Oh shit!" moments easier to deal with afterwards.
Park a 5 minute walk away from any illicit activities.
As for the google activities, check it out here..
External Link/Members OnlyIP worries, I'm on a DSL connection which changes IP monthly so i don't really care about that. If you're really paranoid and don't have a dynamic IP that actually rotates, get a VPN.
Hosting my own email is totally out of the option, I don't trust registrars with the whois info, even if it's protected. Easier to just use outlook.
Unless AW suffers an attack like ashley madison, then stupid me who bought credits on a CC won't get caught
