I'm a little confused why Gaia is participating in these "offers" at all. As far as I can see, they are scams, not legitimate offers, and the most "legitimate" examples of these offers come at the high price of HUGE amounts of spam, for months if not years.
I began to sign up for one last year, but after it asked for my personal information (name, address, etc.) I decided I was not going to participate anymore, and stopped without submitting the forms. Well, they still got my email address, and at that address (which I almost never use), I still receive spam. I have tried to "unsubscribe" myself from as many of those mailings as possible, but my email address has been passed around and around and around.
And this is when I did not even sign up. Imagine if I had given them my irl name and address and phone number.
