Well folks, the mystery has been solved once and for all. And – surprise, surprise – Larry is lying through his teeth. Here’s what he had to say on his blog when someone told him that I had traced the IP addresses and found that the 2nd Dave came from his IP address:
I don’t know if Ed Brayton said that, but if he did, he is full of shit.
For starters, Ed Brayton could be lying, and being the lousy scumbag he is, this is a strong possibility. But even if he is not lying, he is still full of shit. I use dial-up service, and my computer’s local IP address changes every time I log on to AOL, but my brother and I possibly share the same AOL proxy with the same IP address.
Bzzzt. Thank you for playing, we have some lovely parting gifts for you. I can prove it all with the help of a little screen capture program, the ARIN whois utility and an email from the real Dave Fafarman. You see, Dave Fafarman really is a member of the NCSE, so they had his email address. One of my friends in the NCSE office emailed Dave and put him in touch with me. Dave confirmed that he did indeed write the first comment under the Typekey username DaveFxxx, but did not write the comment with the Typekey user name Dave Fafarman.
As I said this morning, I checked the IP addresses for the two and compared them to the IP address Larry used before he was banned and they were the same. And since Larry is now calling me a liar, let’s put the proof out there for all to see and expose who the real liar is. Here is a screen capture of the Movable Type data for the first comment, from the real Dave Fafarman:

And here is the data for the second comment, with the Typekey name Dave Fafarman, the fake Dave:

And here is the data from two old Larry comments from January and February. First one:

And second one:

Notice that the IP addresses for the fake Dave and the two Larry comments are identical – 207.200.116.13. Now, take a look at the ARIN whois information for that IP address and you’ll see that, contrary to Larry’s claim, this number is not a dynamic IP address:

And now look at the ARIN whois information for the real Dave’s IP address:

Notice that Larry is on AOL, while Dave is on SBC. And Larry’s IP is not portable, while Dave’s IP is. And guess where the email from the real Dave came from? Yep – SBC, not AOL.
So here’s the bottom line: when Larry said that someone was impersonating his brother on my blog, he was lying. But then he made it come true by impersonating his brother himself, lying to make his real brother look like a fraud. And then when I caught him by looking up the IP addresses, he again lied and claimed not to be the impersonator. When he said his brother could be on the same IP address as him, he was lying. When he said that his IP address changes every time he dials in, he was lying. That’s a whole lot of lying, and all for the sole purpose of covering up the fact that his brother was telling the truth. Seriously, Larry – get a freakin’ shrink.
Update: For those of you who think that perhaps Larry is not necessarily the person impersonating Dave on my blog using the “David Fafarman” typekey account, you need only look at this post on Larry’s blog. In it, he reprints a comment he tried to leave here but was blocked (because I banned that typekey account when it was proven that it wasn’t the real Dave). The only way that Larry would know that the fake Dave comment was blocked is if he is the fake Dave. Game, set, match – is there a therapist in the house?
