GFI/SORBS – a DDoS Intermezzo

Act 1 • Act 2 • Intermezzo • Act 3 • Act 4 • Act 5
Management Summary, Redistributable Documents and Links
I’ve been stage-managing for a production of The Nutcracker this week, so musical terminology is on my mind. In opera, the intermezzo is a comedic interlude between acts of an opera series.
This comedic interlude is about the “DDoS” – a distributed denial of service attack. What is a denial of service attack?

GFI/SORBS considered harmful, part 2

Act 1 • Act 2 • Intermezzo • Act 3 • Act 4 • Act 5
Management Summary, Redistributable Documents and Links
Yesterday I talked about GFI responsiveness to queries and delisting requests about SORBS listings. Today I’m going to look at data accuracy.
The two issues are tightly intertwined – a blacklist that isn’t responsive to reports of false positive listings will end up with a lot of stale or inaccurate data, and a blacklist that has many false positives will likely be overwhelmed with complaints and delisting requests, and won’t be able to respond to them – leading to a spiral of dissatisfaction and inaccurate data feeding off each other.

GFI/SORBS considered harmful

Act 1 • Act 2 • Intermezzo • Act 3 • Act 4 • Act 5
Management Summary, Redistributable Documents and Links
A little over a year ago the SORBS blacklist was purchased by GFI Software. I had fairly high hopes that it would improve significantly, start behaving with some level of professionalism and competence and become a useful data source, in much the same way that the SpamCop blacklist turned into an accurate, professionally run source of data after they transitioned from being a volunteer run blacklist to a service of IronPort.
GFI’s statement a year ago was:

Preferences pages

As often as I talk about how badly companies send mail, I think it’s always a good idea to highlight when I find companies doing good things.
Today’s example of a company making me happy is Sur la Table. I’ve been on their mailing list for quite a while and do enjoy the offers and information they send. With the advent of the holiday cooking season, though, they’ve massively increased their volume. 21 emails in September, 25 emails in October and 37 emails in the month of November.

Facebook Postmaster page

There’s still quite a bit of concern and worry about how the Facebook messaging platform is going to affect marketing. One thing that may help is the Facebook postmaster page. There’s all sorts of good information on those pages, reflecting the years of experience that their messaging team has in running large platforms.
Some points worth mentioning.

TWSD: SEO Spamming

It’s no secret that I get a lot of spam. It’s no secret that some catches my eye enough to actually write about it here. Today’s spam is an email that actually made me laugh, though. Somewhere, some gardening site paid a lot of money for search engine optimization and got ripped off.
We own the site samspade.org. It’s down now, victim of a major hardware crash, but this was a site with a number of tools for tracking spammers. This morning, I got email about SamSpade.

Another take on the emailpocalypse

One of the strengths of email that instant messaging lacks is asynchronous communication.  With email, you send someone a message and they may or may not respond right away.  Sending somebody an email means that you are not necessarily expecting an instantaneous reply.  In fact, that’s the whole point of not using the phone or instant messaging.  You are not expecting your target recipient to be at your beck and call.
