For all domains? Well, I went through just over 1900 domains from a list. Of those, about 950 were listed with TH. Of those, there were a whopping 119 that listed weaselboy (speedyserver) as the owner, admin, tech, and billing contacts. How happy do you think those people will be if/when they decide to change? Of the total number regged with weaselboy, there are many that are just wastelands (i.e., someone registered it and then left it). Of those that were not regged with weaselboy are a number of domains of people that left awhile ago - this I know for sure, since most of them contacted me when they left.
There are also some very interesting domain names in the list that are obviously not registered, but that indicate that people were just playing around with weaselboy: thsucks.com, weaselboyisintrouble.com, peterisgoingtojail.com, etc. None of those is from me, I have to say, but I do find it pretty funny that he would leave directories like those on the server.
On another note, just so folks can see what kind of "support" they'll get: I sent a note (twice) asking a very simple question, to see how the "support" is: "What is the path to sendmail?" Have not received an answer, and it has been a week (and counting)...
