A WebmasterWorld thread has one webmaster claiming Google replied to a request through his web site's contact us form.
He submitted a couple reconsideration requests to Google and Google went to his site and clicked on the contact us and filled out the form.
I am not sure why they wouldn't reply via Google Webmaster Tools but he says they did not.
Right, but we have the same info@ email set up for contact form and WMT account. This message is not visible on WMT. It's a direct info@Site.com contact with subject ( [#9 figures] Reconsideration Request for mysite.com)! I checked the logs, message came straight to e-mail not contact form, sorry!
Email came as a response to my 3rd reconsideration request, it was a clear reply to my explanation message. Email: I-hid firstname.lastname@example.org I also think that 3 RR is quite many to deserve personal attention! A guess to speed up the communication: "please reply to this email with the details of your clean-up effort."
I've never heard of this happening before but I can see that it potentially could happen.
I'd be concerned that it would be spam or a scam but in this case, it appears to be legit.
