Which probably doesn't account for much revenue.. which is why (I think) they *later* added the paid access.
I guess I have grown too accustomed to the long standing symbiotic relationship between spam warriors and service providers. We rely on you to help us filter our incoming mail, you rely on us prevent or at least diligantly mitigate spam coming from the large number of potential sources on our networks. We're supposed to be in this together, working from both sides of the equation.
This relationship seems very one-sided to me. The service providers charge for their services, and they get more business from paying customers when their spam filtering is better than their competitor's spam filtering. However, I see no equivalent benefit for the time/efforts of the spam warriors if/when the DNSBLs are free. NOT saying they should all start charging exorbitant fees, but I don't see this "symbiotic relationship" you refer to when DNSBLs are free. Am I missing something here?

As soon as the motivation stops being about preventing spam and becomes about making money, you essentially equate yourselves to the various large networks providing transit to spammers out of desperation to pay for their overbuilt networks and meet quarterly revenue goals.
To equate (A) paid access to DNSBLs with (B) DNSBLs giving spammers a pass in exchange for cash... this is very insulting to DNSBL operators. Can you (or anyone?) provide examples of currently well-respected and frequently used DNSBLs which you know for positive are giving spammer's a pass in exchange for cash and which haven't been severely "taken to the woodshed" on public forums. If there is such an example, I'd like to know. (The closest thing I can think of is DNSBL operators giving some of the larger mainsleasers a pass for fear of being sued out of business... but that only emphasizes the riskyness of this business and is NOT profiteering nor "quid pro quo")

the more I think about this the more shady it feels to me.

DISCLAIMER: I'm an admin for SURBL. I ALSO run a separate for-profit DNSBL that requires a monthly subscription payment for access. I even e-mailed Andy off-list to tell him about my subscription based-DNSBL in case that would help him.

When I think about the countless unbillable hours that I've spend creating two world-class blacklists over the past years... (a URI list and an "RBL") as well the time I've spent helping SURBL... I have to confess, after reading Andy's comments, I was about ready to throw furniture across the room.

But, at the same time, I can't help but feel like URIBL's prices seem a bit steep.Then again, maybe I wouldn't think so if my own mail hosting business really did have enough business to generate enough queries to raise alarms. IOW, at the (current) size of my business, these prices seem high... but maybe that is comparing apples to oranges since I don't have the revenue streams that the typical business from which URIBL would require a subscription.

In general, it would be nice if more DNSBLs would create revenue models where smaller organizations would pay just a little per month... and that is closer to what I've come up with regarding my own subscription-based DNSBLs. I can understand the sticker shock when something goes from "free" to being thousands of dollars per year.

But when someone says that all DNSBLs should be "free", and implies that those operating "for profit" DNSBLs are "shady", I'm left feeling angry and frustrated. Running a DNSBL is a risky, time-consuming, and costly business (particularly if the DNSBL is of world-class quality.)
