Hi there. I posted the entry about the new spam control system last friday and am willing to help those that feel their machines are improperly registering as "open proxies". Just send me an email with your IP, date/time of attempted posting and the full error message that results.

My first suggestion to those that want to comment is to actually check your machine and insure that it is not infected/vulnerable. That's why those machines were listed in the first place.

And yes, we plan on tweaking this to make it work better. We will continue to try to balance spam protection with ease of posting.

Believe me, I'd much rather spend my time fixing these types of problems than deleting thousands of spam posts!


No one can post comments? :)

Checking to see if I can yet.


Yes, my IP is now cleared. I went through the process once I got involved in swapping emails with PaulL. When I checked it turned out my whole subnet was blocked because its addressed were dynimically assigned. I couldn't fine evidence that spammers had used any of these addresses specificallt, but, of course, I would not be shocked if they had. The Sobig virus installed a LOT of proxie servers on zombie machines that are always on. Most of the attractive ones are DSL/cable connected.

This is the wrong approach, though. It hurts legitimate users more than it does spammers (they just switch to yet another zombie, or go to forging headers).

It will be interesting to see what SixApart does with TypePad. They are in a bit of hot water with their user base (including me) due to recent major policy changes with Movable Type, their flagship product.

Good products, I suspect very nice people, but the process of growing from garage to something more is painful (been there) and often fatal. It's easy to lose touch with what made you successful in the first place, usually solid understanding of your customer base's needs.

Game companies, of course, never have that problem.

We'll see how long it takes me to get blocked again. At least my system at work should be pretty immune.


Sorry to hear of the trouble.

So today's lesson is, don't underestimate the complexity of reputation in large systems?

(Just thinking about how this might apply to problems in VW reputation systems.)


Testing, if this posts I guess I'm ok :)




i better test too, i guess.


Hi all,

We have an override mechanism in place. If you're blocked, enter the code that shows on the error page and your post will be accepted.

Apologies to anyone who was blocked. We put this fix in under duress. I'm happy that we were able to offer a workaround after a few not-so-short days.

Suffice to say we're here for you, the blog owner and the commenters, we want everyone to have a positive TypePad experience with spam-free comments and easy commenting.
