People seem to come out of the woodwork when you have something working well for you and there seems to be two ways to think about it.
1) Good, your helping those willing to take massive action obtain success. After all, Plenty of people can copy the actual words in an ad, or the pictures, or even the strategy behind it. But nobody, can ever copy the relationship and bond that you have with your customer base and prospects.
2) Keep it to yourself because you invested the time and/or to test what works and what doesn't which could saturate the market by causing more competition for yourself. Worst would be if that fellow marketer steals, copies, or reverse engineers your strategy.
What is your method for handling this situation?
