Get a secure email address? I am not a "meph" follower but I signed up just to see whats what since they are so popular. I've gotten regular emails frequently. Might be some type of security filter they are using. Just a thought.
I can try and post the email if I don't see it up, however someone usually has the info posted before I can check email and log on here. The reddit place seems quite popular and updated as well. I don't understand how that whole part works at all but a quick google or whathaveyou of "reddit mephisto and xx date" seems to work.
The Stan account is fairly active on here from what I've seen. Seems like a good and earnest fellow suffering the effects of moonshot instant fame.
