Blocklists, delisting and extortion

As I’m sure many of you have heard by now there is a new blocklist called ‘nszones.’ This blocklist is apparently stealing data from a number of other publicly accessible blocklists, combining the data and then charging folks for delisting.
This is a scam attempting to extort money from people. The blocklist has no way to actually remove IPs from the parent zones and I’m pretty sure they won’t even remove IPs from their own zones. In this case, the blocklist is clearly a scam, but there are other lists that are actually used by some mailservers that do charge for removal.
No legitimate blocklist will ever expect a listee to pay for delisting. Ever.
I feel very strongly about this. In fact, one of the major blocklists is run off a domain owned by Word to the Wise. Occasionally, I get contacted by folks looking for help with a listing on that list and I will not take them on as a client. I will provide general advice and make sure that they are correctly contacting the blocklist but nothing more.
This is, to my mind, the only ethical thing to do. I don’t even want a hint of impropriety surrounding either myself or the blocklist. Charging money for delisting only feeds the conspiracy theories.
Charging listees for removal (or listing listees so those charges can be a revenue source) is likely to lead to poor quality data and a blocklist that’s not terribly accurate nor effective. Furthermore, if a list operator is unethical or confrontational in their interactions with listees, they’re probably equally unprofessional in their interactions with potential list users. This results in few recipient domains actually using the list to block mail. Lists that charge are not widely used and being listed on them often does not affect email delivery in any appreciable manner.

ESPs leaking email addresses

Two of my tagged email addresses started getting identical pharma spam over the weekend. It is annoying me because I am now getting spam in a mailbox that was previously spam free. The spam is overwhelming the real traffic and I am having to make some decisions about what to do with the email addresses and their associated accounts with the companies I gave them to.
One thing I did notice, though, is that both companies use iContact as their ESP. A cursory check of my other mailboxes shows that none of my other tagged addresses are mailed through iContact. I don’t think it’s very likely that these two individual, unrelated companies made deals with the same spammers to sell address lists at the same time. It’s much more likely that there was a compromise somewhere and address lists were stolen.
Edit: Checked my other account and, likewise, I’m getting the same spam to a 3rd address serviced by iContact. I’ve sent mail to all 3 companies involved and we’ll see how they react.
And, as I was thinking about this, iContact just laid off a bunch of staff about the same time they announced their partnership with Goodmail. Based on past history with companies in this situation, it seems possible this is a disgruntled former employee. I’ve also seen reports from other people noticing spam to addresses given to iContact customers.

Improving the email interface

Want an improved email interface? Then build it.
There’s been an ongoing discussion about adding thumbs up / thumbs down style buttons to email clients. While I am dubious this is a useful feature or something that recipients will use, if there are others in the industry that think it would be useful then I strongly suggest they go ahead and create it.
In fact, there are a couple things that have been asked for in email interfaces that aren’t currently provided. Last October I blogged about adding an unsubscribe button to email clients.

TWSD: Using FOIA requests for email addresses

Mickey has a good summary of what’s going on in Maine where the courts forced the Department of Inland Fisheries and Wildlife to sell the email addresses of license purchasers to a commercial company.
There isn’t permission associated with this and the commercial company has no pretense that the recipients want to receive mail from them. This is a bad idea and a bad way to get email addresses and is no better than spammers scraping addresses from every website mentioning “fishing” or “hunting.”
