Who is this spammer?

I absolutely like to receive mails from people I know and from some services I am using. I hate unsolicited emails and frauds. No one likes that of course. It is important for some services if they have third parties email lists to define themselves when they send some offers like the following:

Have you searched the internet countless times looking for a way to “hack?” Maybe you have searched for a way to download programs, games, or movies for free? Or maybe you have searched for a friendly, helpful, community that offers all that plus more? Well search no more, you have struck gold. Well not quite gold, better… Kwickfix.org!

I consider the message above email spam. The script of this email spam as it appears from those lines above, confirms that it is not professional. It is also not addressed to any one. Most importantly, that email spam came through gmail to a gmail address. The question is how did this person know my gmail address to send me such spam?

Important Note: When some people send such emails, it is very important to define who they are, because of the fact that no one will open an email from stranger. So, sending anonymous messages kills their offers. How could they be professional if they are doing this?
