I wouldn't spend a lot of time worrying about this.

I got some very interesting and abusive emails as part of the openresolverproject.

Most of the people were professional in their requests and we have a dialogue ongoing.  Some I wouldn't even share in impolite company.

Right now there is only one IP that the OpenResolverProject does not probe.  When we share the extent of the problem, most people notice there is a problem and the request falls off their primary concern space.
