Aggressive marketing

I'm on a lots of affiliate marketing lists. Not a lot of females out there, but there is one person who really stands out: Rachel Long. She seems to be doing really well, she's on top of a lot of lists with best downlines. The guy's e-mails are really polite, they always offer something free etc. She doesn't. No, there is nothing free and the e-mails are not even polite all the time. I wonder if people purchace from her just because they want to get her off their backs?
Whatever she is doing, it seems to be working...
