うんと，ねずみ講ではないかと仰ることの理由が
わからないのですが（何も指数的連鎖はないし），
Privacy Statement は以下のようになっています．

Who will see my signature information?
There are several ways your signature information may be shared:

Public Petition Signature pages.
Certain fields will be displayed on the publicly displayed signature
page for all to see. Your email address, street address and telephone
number are never displayed on this page. You are always given the
option to check a box to hide your name, and replace it with the word
"anonymous." You are also required to preview your signature before
you submit it, to prevent mistakes.

Petition Author / Target.
At the close of the petition, we provide all of the signature
information to the petition author with the exception of your email
address and/or street address and telephone number. These fields of
information will only be shared with the petition author and target on
a case by case basis to verify the validity of your signature.

3rd Party Offers.
If you choose to sign up for a newsletter/special offer from an
organization other than Care2.com (owners of thePetitionSite.com)
certain information including your email address will be sent to the
organization to activate your subscription.

これを信じる限り，最後の Step 4 をデフォルトのままにすれば，
署名受け付け時以外のメールは来ることはないでしょう．

あと，前の文の論旨がはっきりしないのですが，
＞それよりも、そのうちの一握りでも通販使ってくれたら
＞ラッキーみたいな邪念を感じます。
というのは邪念というより care2.com がこのサイトを
運営することの合理づける理由として FAQ に
書いてあったと思います．いやなら買わなきゃいいし．
