According to the FAQ[0] of the safe browsing program, they attempt to contact you first, but there is a way to contact them.
What if you can’t get in touch with
the webmaster because they’re not
registered with Google Webmaster
Tools?
Every time we add an unsafe site to
the list, we make a reasonable
effort attempt to inform the
webmaster by sending a notification
to a standard set of email addresses
(e.g., webmaster@[sitename].com;
info@[sitename].com;
admin@[sitename].com).
If my website has been compromised
and is now unsafe, what can I do?
We offer advice for webmasters whose
sites have been hacked here. It’s
best to register your site at Google
Webmaster Tools in advance of any
problems so that we can notify you
promptly and provide more
information about the problems we
find.
If you don’t want to use Google
Webmaster Tools, you can file
appeals with StopBadware.org once
you have removed the infection from
your site. StopBadware.org also
offers great resources for
webmasters who want to learn more
about what they can do to make their
sites safer.
A while ago I submitted my site for review and provided a contact. I got no response. I also got no such e-mail. In addition it seems they only send you a "notification", i.e. an automatic "We've blocked you" and not a human attempt to resolve the issue. If a human had been viewing my site it would have been 100% clear that there is no malware issue. However, since I do make use of certain HTML5 features after prompting the user, I could see why it causes a trigger if they have some half-baked neural network algorithm trying to identify potential malware based on JavaScript source.
If anyone is wondering, the site is a location-based file sharing app. It makes use of geolocation and file uploading capabilities. Largely a quick experiment, throwing an idea out there just to see if there's any need for such an app. It was running fine for a few months before Google decided to block it.
