Are you running Parental Controls on your Mac? – Nathan Jan 22 '12 at 14:45
No Parental controls is not running. – Vineet Bhatia Jan 22 '12 at 14:50
Well, I haven't been able to find exactly what it does, but some research states that "nobody" is a system user that OS X creates (so it's fine) and webfilterDNSd is a system process. If Parental Controls are off, I'm not really sure why this is running, but it is most likely benign. – Nathan Jan 22 '12 at 14:59
Sampling the process gives Process: webfilterDNSd [112] Path: /System/Library/PrivateFrameworks/WebContentAnalysis.framework/Versions/A/Resour‌​ces/webfilterDNSd It looks like its associated with WebContentAnalysis.framework which is likely used by Parental Controls. – Vineet Bhatia Jan 22 '12 at 19:45

Although it doesn't answer your question directly, the excellent

is a web resource that describes many Mac processes.

It describes webfilterDNSd as:

"Process is part of clean OS X install however there is no description available from credible sources at this moment. Use supplied link for related google search."

There's a comment section by which others that know might be able to answer your question.
