Changes at Spamcop

Earlier this week some ESPs started asking if other ESPs have seen an uptick in Spamcop listings. The overwhelming answer (9 of 11 ESP representatives) said yes. I’ve also had clients start to ask me about Spamcop listings. All in all, there seems to be some changes at Spamcop that means more senders are showing up on the Spamcop radar.
Luckily, Spamcop provides us some insight into their data processing. If you look at the current monthly volume graph, we can see some very interesting changes in data.

Spamcop volume graph
Volume of received mail went way up in late September.
We can see, before the volume spike, that the number of reports sent tracked closely to the spam submitted. The number of reports stay reasonably consistent through the volume spike. I think it’s a reasonable interpretation that SpamCop has started receiving some new data sources in the last few weeks. I suspect these new data sources are the ones driving the new listings.
There are people who attribute the increase in listings to new spamtraps coming online. The data does seem to suggest that something brought more data to Spamcop, and a new trap feed is highly likely.
This is just another example of the continual adaptation of filters. Filters are going to try and catch as much spam mail as possible. And part of that is bringing on new spamtraps. Spamhaus does it, Spamcop does it, commercial spam filtering companies do it. M3AAWG has even published a best practices document on creating spamtraps (.pdf download).
If you’re seeing an increase in listings on the Spamcop blocklist, you’re not alone. If these really are spamtraps, then you should look at your bounce handling process and see why these addresses weren’t removed in the past.

Delivery implications of Yahoo releasing usernames

Yahoo announced a few weeks ago it would be releasing account names back into the general pool. This, understandably, caused a lot of concern among marketers about how this would affect email delivery at Yahoo. I had the opportunity to talk with a Yahoo employee last week, and ask some questions about how this might affect delivery.
Q: How many email addresses are affected?

TWSD: Mail known spam trap addresses

One of the things we all “know” is that if spammers get their hands on spamtrap addresses then they’ll stop sending mail to those addresses. This is true for a lot of spammers, but sadly it’s not true for all.
I don’t think it’s any secret that I consult for all types of mailers, from those who just need a little tune up to those who want me to help them avoid filters and blocking. During some of these consulting projects, I use my own spam folder as research and provide information on the spam that I am receiving from them.
A few years ago I was working with a company who hires a lot of different affiliates to send acquisition email. A few of their affiliates had really poor practices and they were trying to figure out which affiliates were the problem. I handed over a number of mails from my personal spam traps, in order to help them identify the problem affiliate.
I told them, and their affiliate, what my spamtrap addresses were. And, for many years I stopped receiving that particular spam. But, over the last few weeks I’ve seen a significant uptick in spam advertising my former client.
I’m certainly not trying to convince anyone that handing over spamtraps is a good thing. But there is at least some evidence out there that they’re not even competent enough to permanently remove traps. I really have to wonder at how sloppy some marketers are, too, that they’ll hire spammers and not at least hand over a list of addresses they know are bad addresses to mail.
I really thought spammers were smarter than that. I am, apparently, wrong.
EDIT: Of course, mailing this spamtrap gets them nothing but a little ranty blog post here. It doesn’t result in blocking, or disconnection from their ISP or their ESP or anything else. I suspect if there was actually an affect, like, say, I started forwarding this mail to Spamhaus or other filtering companies, they might stop mailing this address. Anyone want a 20 year old, slightly used spam trap?

TWSD: Adapt to filters

This morning the new Yahoo! CEO posted about changes to Yahoo! mail. I logged into one of my Yahoo accounts to check and see if I had access to the new Yahoo! mail client yet. I don’t, but I did notice that spammers have adapted to the new Yahoo model of disabling filters in the mail folder. Most of the mail in my inbox has, at the very top of the message “Click not spam to enable links!”
My favorite has to be the animated gif of how to click “not spam.”
Spammers spend so much time and energy compensating for filters, hopping IP addresses, rotating through domains, and specially creating mail for different ISPs. I have to wonder, though, if they would waste less time by sending opt-in mail.
