I also wonder why the scamerr knows my email even though I didn't publish it.
Getting one's email is easy, there are various hacking where user data is leaked (usually contain name, username, email, password and hashed password) and many websites who sold users data.
Not exactly hacking but there are some extensions now in google chrome that can view emails and names. More likely by passing the information.
true, people who e-mail lots of e-mails with the purpose of gadgets are frustrating, I used to get emails containing kidnapping my children, but hey! I am still a teenager and do not have children, other than that he asked for a ransom of 4 BTC, very strange in my opinion, whether people out there have run out of sense to find bitcoin on the right path.
Those kidnappers really want bitcoin specifically? Lol! Anyway, just block those emails so they won't bother you again.
