[IMPORTANT UPDATE BELOW]
This is way too deep into blogging for me, but I'll persevere. Ann Althouse conducted a poll to determine who's more of a hack: Glenn Reynolds or Andrew Sullivan. Althouse is, of course, a Reynolds partisan. I left a comment  on the poll that was critical of both (albeit more critical of Reynolds). Someone then left a pseudononymous nastygram reply .
Thankfully, that polling software includes the first three digits of the poster's IP address. And, it looks like the person who left the nastygram is located in Knoxville, Tennessee. That city is home to... Glenn Reynolds. And, this is the second time something like that has happened: the previous time the IP address appeared to be from the University of Tennessee... the school where Reynolds teaches. (On a sidenote, the nastygram uses the same locution as many other comments that are left about me using pseudononyms on other sites such as Reason Magazine's "Hit and Run" blog; in fact, the comment references that blog.)
Now, I'm not ready to accuse Professor Reynolds of leaving any of those comments; I don't want to falsely accuse people of things. Only a partial IP address is available, and the services I'm using might be wrong. And, who knows how Bellsouth has their network organized? There are also proxy servers and many other factors to consider. So, pending some form of confirmation I'm just going to say there's no way to tell who left the current and previous comments.
The comment is at poll.pollcode.com/0aO_result. The IP address given is 70.153.125.x. The service I used is ip2location.com/demo.aspx and zoneedit.com/lookup.html shows a reverse lookup of adsl-153-125-x.tys.bellsouth.net. (Because the last digit isn't given I tried four different numbers for the 'x').
3/18/11 UPDATE: Since I posted this, Glenn Reynolds linked to a smear piece about me and referenced others telling me to "STFU". The above left open the possibility that it wasn't Reynolds. However, based on him referencing the "STFU", I have no qualms about now directly accusing him of being the person who posted the comments discussed in this post.
 The comment I left using the username 24AheadDotCom was:
Which is hackier: a pound of GOP-buffing PJTV-promoting John Galt snark, or a pound of BHO-buffing Trig-obsessed delusion that very frequently needs a Mental Health Break?
(Note: that's a trick question. Both have equal lack of gravitas.)
P.S. Here's the technique that could have stopped BHO from becoming president that Reynolds and several other bloggers refused to promote before the election:
 The reply from the person using the username "HitandRun" was short and vile:
