Over the time I’ve been here I’ve been talking to a lot of people. I have also acquired a lot of gpg/pgp keys and I see that LOT of people use there real email addresses. I would like to remind everyone that when you give someone your pgp/gpg key THEY CAN SEE THE EMAIL ADDRESS THAT YOU ASSOCIATED WITH THAT KEY. You are NOT suppose to use ANY type of clearnet email service such as: gmail, yahoo, hotmail, etc. If you want to use a valid email address then you need to use an email provider that supports Tor and anonymity. For example I use safe-mail. I’m able to access this email service on Tor which allows me to stay anonymous. You may also use an email such as “[email protected]”.
DO NOT UNDER ANY CIRCUMSTANCES ASSOCIATE A CLEAR NET EMAIL ADDRESS WITH YOUR PGP/GPG KEY. THIS WILL COMPROMISE YOUR ANONYMITY.
