I don't know Jo, but he or she could have been a contact or someone who was, indeed, interesting. Instead, Jo offered me the chance to become financially independent in a few years. I had been spammed.
Most people learn to live with the junk which fills their email and voicemail boxes every day.
Even though I was annoyed at being duped by Jo, I couldn't be bothered enough to take a note of his or her Altavista email account or send a stinging message back. That could change, however, if the egregious Jo found my cell-phone number. One of these is that users are charged when they are called as well as when they do the calling. This actually makes it illegal for someone to send unsolicited commercial email, or spam, to a mobile phone in the US under a provision in the Telephone Consumer Protection Act designed to save consumers money. However, a very murky legal area means that there is no prohibition on sending a short text message to the same device.
