Most of you will remember the penny stock SPAM messages from a fair few years ago.  The main aim of the game is to buy a bunch of penny stock and then do a SPAM campaign to drive buying interest, artifically inflating the price of the stock.  They sell and make their money. It may be a few cents per share, but if you own enough of it can be quite profitable.  Most SPAM filters are more than capable of identifying and dumping this kind of SPAM. 

It looks however like it is becoming popular again.  My little SPAM traps have been receiving a few of these messages over the last few days. 

What is old is new again. It might be agood idea to check that your filters are taking care of these for you.
