I don't know about the timestamps, but I guess it's possible to write several stock recommendations and delete the ones that do not make profits. Also, it is possible to build dozens of sites like DOTS and promote only those who consistently earn money.

I can assure you that I don't do any manipulations with my performance. I don't do almost any marketing for DOTS. The number of my subscribers is very small and if it starts to grow significantly, I'll limit the maximum number of subscribers or raise the subscription price.

I guess there are sites that do manipulate with the performance, so you have to decide for yourself whether you're going to believe me or not.

I noticed that links on my page http://dogsoftheseason.com/subscribe (actual emails) were not working due to a missing script. Now this is fixed.
