Is There Any Reason to Report Spammers to ISPs? 117
marko_ramius asks: "For years I've been a good netizen and reported spam that I get to the appropriate contacts at various ISPs. In the entire time that I've done this I've gotten (maybe) 5 or 6 responses from those ISPs informing me that they have taken action against the spammer. In recent years however, I haven't gotten any responses. Are the ISP's so overwhelmed with abuse reports that they aren't able to respond to the spam reports? Do they even bother acting on said reports? Is there any real reason to report spammers?"

A few may actually behave like this, but I'd be willing to bet that the majority aren't.
I've worked for a large ISP, and we worked with others to fight this stuff. Spam represented a great waste of our resources, and a great distraction to actually providing an actual product for our customers.

ISPs could also install sniffers to watch the rate of outbound off-network port 25 SYN packets, and investigate unusual activity. Oh and don't go saying that this is difficult - just talk to AT&T and the government - they have been sniffing ALL traffic.
But it's VERY VERY rare to find an ISP that does ANYTHING AT ALL to stop outbound spam. Oh sure, they are perfectly willing to install blacklists and filters on inbound, but outbound? Nothing. They don't care. The only way to fix this is to make habitual offenders be financially liable. ISPs also need to make end users liable and start enforcing their TOS, disconnecting grannie and her POS windows box that has no firewall, anti-virus, and is running spambot software.

What ISPs should do is to identify nodes which have actually been infected by a botnet (or are otherwise sending spam/malware) and nuke them in accord with every ISP TOS out there. But, that would be more work, and cut into their revenues, so they don't want to do that.
I run a firewall (iptables), run up-to-date malware scanners, and take responsibilty for what leaves my network. If my security is ineffective, and one of my machines starts spewing spam, I should be cut off and held responsible. But, I should not be penalized or limited because of the actions of others.
Finally, it should be obvious that port blocking, refusing acceptance of smtp connections originating from dynamic IPs, etc. simply hasn't been effective against spam. Spam continues to increase, and will continue to do so until action is taken closer to the root causes - networks start going after originating machines, law enforcement start going after businesses using spam (and, of course, instituting a death penalty for anyone caught purchasing any product from a spammer).

We frequently receive notifications of spam email as well as virus-laden email that has originated from our network. We only respond to the sender if they request that we do (and even then, if it's not necessary and the request isn't polite, we may not).
That means we almost never send a reply to the person who notified us. However, we DO take care of every single notification we receive. If we aren't able to immediately contact the customer and fix the issue (generally a home user with a virus doing the spamming), then we either shut off their service or, more frequently, block outgoing connections from their IP to port 25 anywhere.
