Hi,
 I serve a few thousand domains from my 3 geographically dispersed
tinydns servers, and I'm noticing that they are getting quite a lot of
queries from Cyveillance. I don't like Cyveillance and I don't want them
gathering info about the domains I host. I basically would like to
either block Cyveillance or even better, return 127.0.0.1 for anything
they query.

 Any ideas on how to accomplish this, other than adding a lo record to
each of several thousand domains? I'd prefer a low-maintenance, global
blocking solution.

Thanks,
Mike
