It arrived in my email from "HotCopper Team" and the subject line was "Our stock tip for 2012 is up 600% - Here is our tip for 2013…"
Now to me that looks like Investment advice from the Hotcopper team ... definitely not an advertisement.
No where in the email does it say it's a paid advertisement.
Looking at the volume it looks like a lot of people bought in as a result of receiving the email.
