I think he tried to use my server, but for some reason he did not liked it :P

We have a member who is attempting to run an extremely heavy web crawler which he claims is performing around 1.6million queries per second.  After being throttled by his own ISP and google, he has turned to OpenNic to satisfy his demands for DNS.

Several members have spent hours trying to explain the situation to this user.  Ideally he should be running his own DNS server, but he doesn't want to dedicate any of his CPU time to that, and he claims he can't run his own because it would buckle under the load demands he needs (and yet somehow he expects OpenNic to satisfy this demand for him)...

We are unable to make any progress with him, so we are moving on to the next step -- banning his IP addresses.  If you are running a public DNS that is receiving extreme sustained loads, please look over the following list and block his queries as necessary.  The user is NOT on static IPs, so this information may change.  You should also watch for a high rate of queries for *.hallowe.lt as a sign of the user's web crawling.
