You know what might be a worthwhile project Ken?
In order to simplify things, I'll bet the promoters have people segmented into a few broad lists.
If you're on List A, you'll see InsidersLab and VictoryStocks regularly, but will rarely if ever see AwesomePennyStocks.
List B gets APS more frequently, but etc. Etc. Etc.
I say this because I hear people repeating the same complaints about what emails they have and haven't gotten again and again.
If we could get everyone to post all the emails they got with times, we could see if there are groups we fall into pretty easily.
