I get around 10 to 15 "investment opportunity" emails every week from unsolicited spammers/scammers not just the generic Nigerian prince, or friends emails been hacked and asking for "send money now to rescue me from Shanghai airpor" - but ones for pension schemes, property investment and other such things. I think I'm targeted for investment spam as I've stupidly posted my email in investment forums on other websites before, I will admit I didn't know what I was doing at the time, now I don't add my personal email to any public website.
