Trying to find a specific bot ... (please help me...)

I could use a little help on this. Need to find a specific bot... and I can't find it.

I'm trying to find a specific bot someone told me was available... somewhere. :confused:

It's a bot (or crawler or script or software) that basically crawls the web at specific sites and scrapes specific email addresses. Don't worry, it's not for spamming, please read on. Specifically, you provide a name (for example purposes, let's use: 'John Smith') and it will search out within specific sites such Facebook, Linkedin, etc. as well as possible association sites (Real estate (Realtor) associations or insurance associations or contractors associations., etc.) or overall websites, (you can leave it as an open internet wide search or specific sites search) searching for any and all email addresses that can be found tied to or associated with the name of 'John Smith'.

The final objective would be a list of names or variations of the name (perhaps) such as John Smith, John D. Smith, Johnny Smith (or whatever) along with the corresponding email addresses. Or it can be set as a specific name or root name only (John Smith) with corresponding list of all email addresses of John Smith.

A programmer I am dealing with tells me that he's seen one out that is able to do what I am needing, but he could not remember who it was made by and in turn I have been unable (at all) to find it.

Anyone able to direct me to a specific software or bot able to do as specified? Perhaps you have made one yourself? I would be so appreciative for any information anyone would be able to provide me.

Thanks in advance to anyone that can answer me on this,
