SE use of private account information

Hello All.............

Ive been investigating the use of "KeyWord Ranking" at: directresponse.com a site that offers specific ROI data on keywords you have listed at Pay Per Click engines like Google, Overture, etc.

In response to my question to Direct Response "How do you get the actual cost that I pay for a particular word?" I got this answer:

we get the cost data directly from your account with the ppc engine. the cost data will be the total spent on a word per day. we then do a calculation to report the cpc - which will be the average daily cpc. We have data exchange relationships with the top ppc engines which provides us with limited access to your account with Overture for example. This limited access allows us to pull your spending data.

Now I'm just an amateur at this but I was really shocked! They make it sound like it's no big deal........ and maybe it isn't..........but the SE's sharing my private account data (ANY of it) with someone sounds very unethical to me. If they share any information who is to say they don't share all of it? And to whom for what?

I would very much like to hear some feedback on this issue. Is it just that I don't understand the "issue"??

Thanks!
