I did the SAME thing! In two months of doing surveys, I made a whole two dollars and got a couple of boxes of free cereal. In my first month of doing MSing, I made almost $200 and spent a lot less time doing it!
As for the so-called "winning" notices,odds are that NONE of those supposed "winning" or "designated befactor" notices are real. I mean, do you now or have you EVER played any of these lotteries that you have supposedly won"? As they say, "You can't win if you don't play."
As for those alleged "inheritance" notices, C'mon. I mean, they knew how to contact you by email. If a "real" relative died, wouldn't they at least have your address or telephone number too if it was legitimate? And they're always from a foreign country where the U.S. internet laws are not applicable! And, how many relatives do you have that you're "close" to in these countries?
Just keep deleting them and flagging them as spam...and all the best with your MSing.
