NetNanny CEO Clayton Ostler publishes misleading article with inaccurate claims about blacklists and their relevance to web filtering solutions.

Netnanny is a well respected content control provider, and we acknowledge that, but being a respected industry leader means behaving with a degree of integrity. Delivering factual and accurate information to the public, and to its clients. I believe that the article posted recently on Netnanny’s official company blog, written by the CEO of Netnanny Clayton Ostler,
which can be found here. Falls short on both integrity and accurate facts.

In the article, Mr. Ostler expresses his general attitude towards blacklists, which comes across as a comical and lighthearted dismissal targeted to his potential customers. To the average reader, it might seem relevant, but to the developer, it could be a bit insulting, even infuriating. Clayton Ostler goes on to explain that blacklists are totally useless for web filtering purposes. And, eventually he informs the reader that the only effective, practical solution for web filtering must of course be purchased from Netnanny.

Mr. Ostler also claims than there are only three blacklist providers on the web, which would be true only if you built a time machine and traveled back in time to 2005. And of course it is 2017, and he doesnt mention once. Which is highly suspect, considering that is, in fact, the worlds leading publisher of domain blacklists for web filtering platforms and applications in 2017.

"I've done the footwork and scoured the web - there are a lot of blacklist resources out there, but most of them were blacklists that haven’t been updated since the early days of the internet. The industry leader of internet blacklists, Dan's Guardian, used to provide a free list that was well maintained. Now they only have paid solutions. Internet Blacklists are Obsolete: Keep in mind that any blacklist will be outdated the minute you download. Why? Because thousands of new webpages are popping up each and every day."

Let me respond by first pointing out that he apparently didn’t “scour the web” very hard, as a simple google search reveals is a website that is not hard to find. Also, “Dansguardian” is not “the industry leader of blacklists” nor was it ever. What Dansguardian was, is a web filtering plugin for Squid Proxy, it was not a blacklist provider, nor was it ever. Shalla Secure Services LCC, through its websites, and, was a blacklist provider, which presumably is what he meant to refer to. Blacklist by Shalla are no longer maintained.

And while it may be true that the blacklist quality from shalla was never that great even when it was maintained. Blacklists from however, far surpass anything ever produced by shalla, even when it was maintained. Mr. Ostler then goes on to claim that “any blacklist will be outdated the minute you download it”

Intelligent people form conclusions based on facts, not nonsense, and certainly not biased sales pitches, or silly opinions with no merit. Again, I would point out that apparently hes never used blacklist services by and I would contend that if he had, perhaps his opinion would be a bit different.

It is true that one would be foolish to rely only on blacklists for modern effective targeted inline content control, it would also be foolish to update your blacklists once and think that everything is fine. Blacklists need to be processed and refined every day, and they need to be distributed to your web filtering solutions at regular intervals to ensure the most recent data and corrections are available to your systems.

Furthermore, I would also contend, that through his attempts to completely discredit blacklists as a proven method, which adds yet another valid and extremely effective layer to an overall effective web filtering strategy, demonstrates his propensity to value sales rather than reporting on the facts.

And it becomes clear that absent of any valid facts behind his arguments, the entire article becomes a mindless, meaningless exercise of a marketing campaign. A puff piece to convince consumers to abandon all hope of building an effective web filtering strategy.

Development at is ongoing, and while there is much work to be done, blacklist quality has never been better, and we will continue to discover and develope new ways to improve our systems, expanding our subscriber base, while developing new plugins and modules for our autonomous domain addition and removal system, which logically discovers, adds, classifies, and removes domains for the freshest updates, multiple times , each and every day. Giving network administrators a new low cost, viable alternative, to breath new life into both existing and developing platforms. is, the worlds current leading publisher of blacklists for content control platforms and applications.
