Marketing to businesses

“If you do stupid things, you’re going to get blocked,” says Jigsaw CEO Jim Fowler in an interview with Ken Magill earlier this week.
Jigsaw is a company that rewards members to input their valuable business contacts. Once the addresses are input into Jigsaw, they are sold to anyone who wants them. Jigsaw gets the money, the people providing information get… something, the people who provided business cards to Jigsaw members get spammed and the people who downloaded the lists get to deal with a delivery mess. Sounds like a lose for everyone but Jigsaw.
Except that now Jigsaw is listed on the SBL for spam support services. Well, that’s going to cause some business challenges, particularly given how many companies use the SBL as part of their filtering scheme.
It’s hard to think of a situation where I would appreciate someone I gave a business card to providing my information to a site that then turns around and lets anyone download it to send email to. I know, I know, there are a million companies out there I’ve never heard of that have The Product that will Solve All my Problems. But, really, I don’t want them in my work mailbox. The address I give out on my business cards is, for, y’know, people to contact me about what I’m selling or to contact me about things they’ve already purchased from me. That address is not for people to market to. I have other addresses for vendors, and even potential vendors, to contact me.
Jigsaw clearly facilitates spam to businesses by collecting email addresses and then selling them on. This is a drain on small businesses who now have inboxes full of valuable offers to wade through. Perhaps their stint on the SBL will make them reconsider their spam support services.

Beware: Phishing and Spam in Social Networks

Trend Micro warns us today about how spam and phishing can hit you even in the closed ecosystem of a social networking system such as Facebook. Malware abounds. And in the social network arena, just like anywhere else, “using your account to send spam” is a common thing for the bad guys to want to do.
In Rik Ferguson’s investigation (which I read about on CNet News), he came across a link to a URL that asked for his Facebook credentials, supposedly necessary to allow installation of a specific Facebook application. Once the credentials were handed over, the app immediately spammed all of his Facebook friends, sending them a bogus notification, attempting to draw them into visiting the phishing/malware URL, with (one assumes) the hope of spreading the infection even wider.
He’s a researcher for Trend Micro, so he knows what he’s doing. But for the rest of us, this highlights how necessary it is to be careful with who you give your usernames and passwords to. In my opinion, it’s never safe to take your username and password from one site and hand it over to another site. Some social networking make the problem even worse by blurring the lines between safe and unsafe by asking for usernames and passwords to third party accounts, but you just can never know with 100% certainty which sites are legitimate and which ones aren’t.

People are still talking about the White House spamming. At Al Iverson’s Spam Resource there are two posts, one from Jaren Angerbauer titled Guest Post: Email and the White House and another from Al himself titled White House Spam, Signup Forgery, and GovDelivery. Both are insightful discussions of the spam that the White House has been sending. Over at ReturnPath, Stephanie Miller talks about how the publicity surrounding the spam is great PR for permission.
Stefan Pollard has an article at ClickZ looking at how an apology email in response to a recipient visible email mistake can actually make the fallout worse.
Web Ink Now documents one recipient’s experience with a bad, but all too common, subscription practice.

Yahoo and Spamhaus

Yahoo has updated and modified their postmaster pages. They have also put a lot of work into clarifying their response codes. The changes should help senders identify and troubleshoot problems without relying on individual help from Yahoo.
There is one major change that deserves its own discussion. Yahoo is now using the SBL, XBL and PBL to block connections from listed IP addresses. These are public blocklists run by Spamhaus. Each of them targets a different type of spam source.
The SBL is the blocklist that addresses fixed spam sources. To get listed on the SBL, a sender is sending email to people who have never requested it. Typically, this involves email sent to an address that has not opted in to the email. These addresses, known as spamtraps, are used as sentinel addresses. Any mail sent to them is, by definition, not opt-in. These addresses are never signed up to any email address lists by the person who owns the email address. Spamtraps can get onto a mailing list in a number of different ways, but none of them involve the owner of the address giving the sender permission to email them.
Additionally, the SBL will list spam gangs and spam supporters. Spam supporters include networks that provide services to spammers and do not take prompt action to remove the spammers from their services.
The XBL is a list of IP addresses which appear to be infected with trojans or spamware or can be used by hackers to send spam (open proxies or open relays). This list includes both the CBL and the NJABL open proxy list. The CBL list machines which appear to be infected with spamware or trojans. The CBL works passively, looking only at those machines which actively make connections to CBL detectors. NJABL lists machines that are open proxies and open relays.
The Policy Block List (PBL) is Spamhaus’ newest list. Spamhaus describes this list as
