Guys,
If you must use a (really) smart phone for punting, make sure you don't send any e-mails from it that come from any address other than your dedicated punting e-mail address. Ideally set up your punting e-mail address ON your punting smart phone. Only ever use this phone for punting and punting-related research such as reading uk punting. Never use it for civvy telephone calls or e-mails - and definitely not to access social media accounts. Conversely, of course, never use a civvy phone for punting activities. That way what happens on the secret phone stays on the secret phone.
